Thanks girls, I really appreciate your replies =)
i spoke to my boyfriend about all this last night and he's being as supportive as he can be, which is what I needed to hear.. He thinks my parents are being unfair and shouldn't expect me to move out the minute our daughter is born. If I did have to, he would eventually move in with me, but that wouldn't happen for a while because he's only just got a pay-rise, he needs to save up a lot of money before he can even think about moving out, and he needs to make sure he can get a job here straight away. He lives about 250 miles away from me at the moment, so I doubt we'll be living together for a while yet.
He's more than happy to give me money every month, though, so financially we should manage, as i'm entitled to a certain amount of money each week as well. Money will be tight, but i've managed to get a lot of baby stuff already, so i'm pretty sure we'll cope.
I'm going to talk to my parents about it, I want them to realise that I do want to move out in the next year or so, but for the first couple of months after the birth i'm going to need time to get my head together, and moving out straight away won't be an option.
I got to hear my baby's heartbeat again this morning, when I saw my midwife. It made me smile, I love hearing it.. And when she told me everything was ok and that she could feel the baby's head etc. I couldn't help but feel attached to my little one again.. So that's a good thing, i'm hoping the negative thoughts I was having weren't my true feelings.
