Oh man, I feel the same way. I don't think it's selfish at all. I always wanted kids but being so far away has made me have doubts. I'm super close to my family (see them 2-3 times a year) and it breaks my heart thinking that they won't be able to be around as much. They're a huge support. Meanwhile, my husband isn't as close to his family as I am to mine, and we would have little to no support if we were to have kids over here. He's more optimistic about it, but I'm the realist and can see exactly how it would be. It makes me think that a childfree life may be the way to go here, whereas if we were back in the US I'd be all for having kids... it's something I'm really torn on.
My husband and I have talked about it a bit, nothing too in depth or serious. We're in no position to potentially have kids right now. If anything, we'd probably wait 2-3 years. While he'd prefer having kids, it's not necessarily a deal breaker for him... he considers the pros and cons of both.
There's a possibility of moving to the US one day, but we'll be here in the UK for a while as he's in the army. He doesn't want to be in the army forever, though.
I'm turning 30 this year and realize that my bio clock is starting to tick. In addition, I have PCOS (luckily it was caught early when I was 18, was put on medication and I've had no issues since) and it may take a while to have a baby.
My oldest sister likes kids, but never wanted any of her own (while her husband is definitely NOT a kid person!). She has pets instead! My middle sister has 2 boys and a girl, who are the best kids ever.
