Hi iambren! Welcome to Divorcing/Divorced!
Before we even get started, I have a few things I'd like to say. I'd like you to know that most of the opinions I give you are going to be christian and based on what I believe the bible tells us to do. I'm not going to

at you because that just shuts people down, but it won't just be a "you're okay" hugfest either, okay? Next, I personally believe in not judging people because that is not my job. That is G-d's job and I would not DREAM of presuming to step in on Him!

So the way I see it, we have ALL sinned. Now some folks see "divorce" as the world's biggest sin--or "adultery" but I see it as a sin like any other sin and that is a behavior that displeases G-d. Lying to get a cookie just does not destroy lives like adultery does! So just so you get a feel for where I'm coming from, I'm not going to tell you that you should have done THIS or should not have done THAT because I wasn't there and I can not judge. Okay?
Now that we have that clear, let me just say that I notice you are not in your early twenty's so I am going to assume that you have a little bit of wisdom just from living here on this earth for a while. I'm also going to assume that you are a Christian and do want to live a life that is pleasing to the Lord. That being said, you ask:
I'm into the whole grieving process,day at a time, when guess who steps into my life? An old clasmate, a widow, a very "willing" widow. She has made her availability known and as deprived as I am for so long it's VERY tempting.
Dear brother, this one is easy.
Col. 3:23 tells us: "Whatsoever you do, do it heartily as to the Lord, and not unto men." I do understand that not having sex for a long time is enough to drive a person just MAD

and that when it is offered after a long "dry spell" it is like dangling food in front of a starving person. I speak from experience. But when G-d created sex for us, it was meant as a gift between committed people to bind them as one before the Lord. In a normal way of talking about it, yes, sex is a physical need and pleasure but it does have a spiritual element. So you are single and not legally bound to any one person right now--but just think of this: as you are having sex with this "willing widow" would you want G-d standing there joining into that union? Would you be able to have sex heartily as to the Lord? I know it's sort of a freaky concept but when you are married and honor your covenant and vow by having sex, you CAN have wonderful, crazy, fulfilling, toe-curling sex as to the Lord because He created it to be that way! The point is to obey G-d and do what HE wants, whether it's easy or not.
So I would just suggest that you think on these things. I do get it--it IS not just tempting, it is ENORMOUSLY tempting!
I Cor. 10:13 tells us: "No temptation has seized you except what is common to man. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it."
Next you asked:
Questions: My dr said don't see her cuz it will interrupt my grieving, why is that bad? What happens to you when you don't grieve all the way?
I'm assuming by "my dr." that you mean like a counselor or therapist or maybe a GP who is a friend who also give you good advice--that kind of thing. Is that correct? This is actually a really good question!
I know everyone has heard of "the five stages of grief" and thinks that it's always like that, and we go in order, etc. but in real life and from my own experience I have to say I disagree. It's kind of a good model though! I think you'd understand the part about the shock--that part where you first hear about it and you feel a zillion feelings at once but also sort of feel like a zombie. Maybe that part was during your marriage when your heart finally disengaged so much that you were just numb! And I bet you know about the "it hurts so bad you can't stand it" stage. Maybe this happened at the very end of your marriage and parts of it were also like as the divorce was being filed and finalized. It's the part where your heart has been shot out by a shotgun. Okay so a next common phase is the reminiscing phase, and I usually see this one go one of two ways--either you look back and go through old photos and think "We used to be so happy" or you look back and think"Wow I never was happy for like thirty years!" Obviously memories can be tainted but I'm just saying that there's a point at which you sort of look back and try to relive some of that. Maybe what you're doing NOW is going back to relive the good love and sex you THOUGHT you should have had all your life.
The final parts of the grieving have to do with your becoming disentangled from your former spouse and your old marriage and sort of changing their role to "past relationship." This part can go back and forth for a bit because when you're with someone for a lot of years, there are things that keep you entangled with them like kids, child support, birthdays, even sometimes possessions! And this part needs to be all the way worked through or what happens is that you haven't really finished #1 and you rush headlong into attempt #2. You give #2 maybe some of the parts that aren't entangled but you aren't all the way free and you aren't finished, and you end up 1/3 invested in "past relationship" and 2/3 invested in "current attempt" and NONE of them work! Then you end up with TWO relationships that fail! And at least in my experience, I've seen a lot of people get sort of STUCK here because they never quite take the time to complete the process and be fully disentangled and fully reinvested in themselves and their new life.
Sooo...does that make sense? If you do jump in now with "willing widow" you may temporarily get some physical needs met (this is true) but it would not be honoring to G-d and you would be partly invested in your past ties, partly invested in some ties to "willing widow", not completely, fully invested in yourself and your new life, and it will most likely all come crashing to the ground like a house built on the sand. I do understand that waiting and not having those urges met is crazy-making, but I would strongly encourage you to take the time now to get yourself and your life straightened and finalized. Take the time to focus on pleasing G-d and being the man He created you to be.
