Well, the biggest change in our case was that she basically did not want to be touched for the whole pregnancy plus a full year afterwards. To provide some context and what I mean, she'd get annoyed with holding hands, and really frustrated with hugging. Physical contact is big for me, so that was really rough. Then, she convinced me that every pregnancy is different and that probably wouldn't happen the next time (it did). It's been over a decade, and I've basically just come to terms with the fact that sex really isn't a part of our relationship anymore. That was a really, really difficult thing to adjust to, but I did adjust to it. I eventually saw that it had to be a choice, and had to ask myself what was more important. I decided that I liked my relationship with my wife and my kids better than I liked sex. I'm not going to try and convince you that it's better; it's not, it's just different, and I'm good with that. Definitely not everyone would be, YMMV.

I don't want to frighten you, OP, I'm just telling you my lived experience. It really is different for every person, and having kids is not an easy thing, so it's going to change you. You can't say how your partner may change any more than you can know how much you'll change in five years. Only you and your partner can decide what you're both willing to put up with. If you want to stay with them, do it. If not, don't.
