Am new becoming a christian still aren't there totally it's been over a year of long hard thinking and reading but am finally going to church on sunday and try to find what i've been looking for 
Anyway the question i have is about sex, if i become a "fully" christian should i stop it with my boyfriend. We have been together 5 years, we have a children together. Currently we don't live together, he actually lives 500 miles away lmao I actually lefted the home because of the problems that we were having and it wasn't fair on anyone, but i never lefted the relationship because love is never easy and it's a hard road, you just can't give up even though the problem we were having many people would have "dumped" him for it, but in my heart and mind i already made that commit to be with him until death do us part, yes i lefted but at the time i felt it was the right thing to do (It's complex and can't go into to fully he didn't cheat on me or anything like that), We are working on our problem and i've always felt he is the one for me. Anyway when we do get together we do have sex not because we have to, if i wasn't with him i won't be out doing it with anyone and the same is for him, it because we love each and it does i feel creates a bond with us. He is not a christian in fact he has never been in a church due to his mother saying she didn't want her children to be forced ideas on them or whatever. I was actually brought up a catholic for many years until i lost faith. Yes we will eventually marry, that i am certain we wanted to get married many times before but "things" or should i say problems got in the way.
So the question is how to approach this ? what do i do ? Also from my understanding we shouldn't marry someone who isn't a christian why is this ? is it wrong ?
thanks for any advise you have
