I should make it clear; I'm not confused about whether to have a baby with him (nope), I'm confused about why he wants to.
We're both expats as such, I'm from the UK, he's from a West African country but has been living & working here for several years, my neighbour, his friend (from the same county) introduced us.
He was very keen from the start, I was flattered but cautious and got involved partly because I'm a bit lonely tbh (and he's v attractive 
) but saw it as fairly casual. There are things about him that make me think he's not exactly backward inn coming forward with women .. another reason I've seen it as casual.
He recently said he wanted to have a baby with me, which totally surprised me and made me think wtf. We've only been seeing each other for a couple of months roughly. I said very little, but it's been raised again - in a weird sort of jokey way, with his mate/my neighbour while in the car (he jokily his friend to open the door for me because "she's pregnant you know" and his friend played along saying things like "oh, is she, I'll be careful" or words to that effect).
I was not amused and it was obvious so they didn't carry on, buft wtf could this be about?
I'd previously asked him if he had any kids (he's a good bit older than me, he's been sheepish and vague about his age, I'm guessing he's late 30s, I'm early 20s) and he said no. That a previous gf had had a termination but that was it.
At first I thought it might be something to do with being "older" and not having had any kids yet; because I know from doing a placement in the country bordering his that people tend to have kids relatively young, and it's common to meet guys who have several children by his age. That he's somehow putting himself under pressure to catch up and he's gotten carried away. But I'm really mind boggled. I also wondered about visa issues but he apparently has a visa to work here, in a developed, pretty wealthy country so .... ?
It has put me off continuing the relationship tbh, but I didn't want to end it in a kneed jerk reaction. I felt like I was being manipulated/stage managed in that car and I'm dwelling on it.
