I have been seeing my current DP for nearly two years. The age gap between us is quite significant - 23 years (I'm mid-twenties) - but it doesn't bother me at all. We are very similar personalities, etc. and if anything I am the more mature one .
He has two now-teenage kids from his previous marriage, which ended before we got together, and doesn't want anymore. Since I was quite young, I didn't think I would want to have children. I went through a bit of a phase of thinking maybe I would, but for lots of reasons I have decided I don't want them. It's not to do with the fact he doesn't want them, I genuinely don't think it's right for me. I joined MN to find out more about children and child-related things, because I have no younger siblings or much experience of children or babies, but am still here because it's addictive!
The problem is, DP has been convinced from quite early on that I would be 'a great mum', pretty much totally based on the fact that I do like babies and will make a fuss over one if I meet it. But to me it's like, I really like dogs and make a fuss of them too, but I don't want one of my own. But he is convinced that I will want children at some point, and will regret being with him, having 'wasted time' (when I could have been making babies presumably ).
I don't think he is going to end the relationship on this basis, as there is nothing else wrong with it, but it makes me uncomfortable when he says 'You will meet someone more your own age, and decide you want children'. It's like he can see the end of our relationship already! It's also annoying that despite how much I say I've made up my mind, he won't listen.
I don't know how to make him see that I know what I want, and it doesn't exclude him.
