Beth, had I read nothing but your opening argument I would have said "wait 6 months!!!" and "wait for your husband to be ready!!!" but since we have talked extensively and on numerous occasions about this issue I will take a slightly different stance.
6 months doesn't sound like too much, the thing that concerns me is the sheer number of times that its "wait another 6 months." If I remember right first it was "wait until April 2006" which has now passed-- last summer that was the goal. Then for a while it was "wait until August 2006" because of a friend's wedding." It went back and forth there and then became "wait another year-- December 2006" so you could pay off debt. I think these are all really good things, your husband wanting to be resposible and you will be *really* glad when you guys aren't struggling with money nearly as much as dh and I.
However, there comes a point when it becomes excessive and in my opinion its getting there rather fast. How long can you push a woman who has the baby bug? How long can she be expected to patiently wait? You need a goal, a date, it is not reasonable to go through this much of an emotional roller coaster on this issue. So he needs to committ-- which maybe is a struggle for him. You struggle with the opposite-- waiting. I know, I am just like you!!
Now Beth think back to your one regret (and since you share this on a number of threads I trust this is not a breech of confidence) ..... when you were dating your husband and you kept pressuring him about getting engaged, when is it going to happen??? He was too cautious and you were too anxious. Sound familiar? It is this exact same situation!!!!
You are both essentially wrong. He is wrong for expecting you to sit around, not have a goal, and just wait until it all feels good for him-- who knows when taht will be at this rate!? And you are wrong for pushing. What a difficult situation!!
I do hope that you two can sit down and have a real heart-to-heart. He needs to see that essentially on issues of this sort he pushes you to the breaking point, as far as he can, and then when you break down he can't figure out why. Um hello? I don't believe in aggravating your spouse, this is very wrong in my book. He doesn't mean to aggravate you, I am sure, but he is. I hope that he can really try to be in your shoes and picture this. Try to put it in parable form telling a story about a girl who dreams her whole life of being a mommy.... somehow put it in words he can understand, and that you want this to go much better than the engagement thing. Sometimes it helps for me to put it in story form for my husband, although this might sound silly, talking about a parallel situation or couple sometimes helps it not be so personal.
