Preggydonuts, there is somebody else on this board in almost the same shoes as you..
You said "I could move...". Of course you could. Your Mum thinks that they'd be running you out of town, well, perhaps that's one way of looking at it.
But it'd be in your interest to move away too, so don't stay just to show then that you won't go!!
If OM and his wife are going to help towards the move, then I might accept the money and move. Closer to your Mum??
NOW,,,,,,,,,, she is advising you to terminate. But wait til there's a tiny baby to cuddle.
In the meantime though, go to your gp and tell them what's happened. You need someone who'll listen to you and give you a chance to think everything through, properly and quite quickly.
ARe your other three at school? Would you be able to work? Would it be just the baby that would need childcare if you went back to work?
Some people might say, 3 children, 4 children, what'#s the difference? or, it could be the straw that broke the camel's back... ONly you can tell.
