I had been with my DD's father for 2 years before it happened - he was ok to begin with but walked away when I was 3 months pg (claiming he couldn't deal with it) saw me again at 7 months pg and has been there on and off since (she is nearly 6)

With this baby it's 3rd unplanned pregnancy. First one found out when I miscarried - he was ok through that but it was never spoken about. 2nd one he was pushing for termination but ended in another miscarriage (both times I was on the pill) we split for a month and he withdrew and refused to deal with anything and we both shut each other out. Then this one was another surprise as I had just started depo shots but again he pushed for a termination I said no so he wished us both dead and I haven't heard since.

Hope your sister pulls through this trying time
