Oh no Solo!!! Your BF sounds absolutely horribly insensitive!! How can he just assume that you will get a termination?! It really seems like he doesn't want this baby at all! Would you consider having the baby alone, i.e. if he doesn't want to be a part of it all?
If I were you, I would feel that falling pregnant now, after being unable to fall pregnant for such a long time, is a true miracle, so I would say go for it if you are at all able to.
When I fell pregnant my boyfriend and I were only together for a bit more than a month and since he is almost 6 years younger than me I wasn't at all sure how he felt about having a child now. So when I was going to break the news to him I prepared myself to tell him that if he wasn't interested that I would raise the child alone and he could sign a contract saying he will have no rights to see the child but also have no responsibilities.
Lucky for me he was over the moon with happiness and we eventually got married and he's been super involved and supportive.
