Hi Pikasam...I was wondering...
I know your relationship ended because your partner wanted children. Did you find this issue became an ever increasing tension in your relationship over a number of years or did it "suddenly" become an all consuming issue?
I have a colleague in a similar situation...nothing has been said - her partner doesn't say much at all on the topic however, his closest friend told her recently...that her partner often says that he's "sure she'll change her mind any day now"...
= bad. Very bad.
My relationship was fine until we made the decision to move in together (after nearly 4 years of single togetherness). I guess at that time, it forced him to consider that this was going to be a permanent thing, and what that meant for his life down the track. Every time the subject had come up in the past, he'd pretty much ignored it or paid lip service, until it got to the point where he wasn't able to do that any more...
I guess the kicker is that all relationships are different and unique to the people in it, so I can't say how this would pan out. My thoughts would be that the first step would be for them to be completely honest with themselves first, as to what they want. Why does he want a kid? Why does she not? What would it take to make that answer different (if anything)?
The big Q - are you prepared to walk away from the relationship in the hopes of finding a new one? Is the abstract idea of having a kid worth that to you?
The interesting thing for me was - he was prepared to walk, and I was equally prepared to let him go. I had, and still have, the things that make me happy. It was a no contest between keeping the guy, and keeping the things that define my life. I wasn't interested in sacrificing myself, and I equally wasn't interested in forcing him to give in to me, having to deal with his resentment every day of my life, and still waking up every morning wondering if this was the day he would change his mind again, and leave anyway.
I know that there are very few people who have my conviction, so I can't say that would work for everyone. I really wish your friend luck. My advice would be - now that she knows, put it out in the open, and deal with it from there with honesty and respect.
The other thing that occurred to me though, re-reading your post, was - what if he's wondering about her "changing her mind any day now" because he DOESN'T want kids, but thinks she does? And doesn't know how to bring it up for fear that he's denying her something? Argh, I wish people would talk about this!
Sorry for the rant... :-)
