I agree with bj - there is almost no 100% way of ensuring you don't get pregnant other than abstaining.

From what I am reading in your posts he seems to be thinking about himself and guilting you by saying 'it was all going well, this will affect it' (sorry not the exact words, I'm just really bad at quoting properly) You need to think about yourself and your partnership and it doesn't sound like he is thinking about the both of you. I also think it would be a good think to stay somewhere where you will be supported. There are lots of options and help for single mums. There are lots here who would be able to give you great advise. And staying with a partner who isn't supportive of your pregnancy and baby will be even harder work than it would be if you were single.

I'm sorry things didn't go better. lots of :hugs: in the mean time
