I'll try and keep this short and simple - I slept with a woman (friend of a friend) and used protection. It didn't work and she ended up pregnant. Now she's almost due and she's been a complete bitch to me the whole pregnancy. I've tried to be there for her and the kid and done my best. She won't let me be involved, won't even let me have a say on what the name of my child will be. And now for the best bit - she earns more than me, owns her own house and drives a BMW. I've just finished uni and am having to pay off my student loan and am very short on money. She's said she's going to go through the CSA to get money from me (I said we should discuss it to come to an amount that she needs and I can afford). The amount the CSA calculator says I need to pay is ludicrous. I honestly can't come close to affording it.

This may seem more of a rant but I don't know where else to turn. What can I do? I've at no point had a choice in this. I thought using protection was a clear enough sign I don't want a kid. She's had all the choices - whether to keep it or not, the name etc. And now she just wants to use me for my money.

EDIT - I'm in the UK, not the States. Also, I will be getting a paternity test, but I'm almost 100% sure its mine.
