Sorry my message was really cold - I didn't mean it to be, it's just my automatic self preservation kicks in when thinking about situations I could have ended up in myself, hence the robotic thought process of what I would do.
I do really feel for you OP, it's an awful situation and I hope you're ok.
Some people are absolutely fine bringing up a baby with no contact whatsoever with the biological father - which seeing as he is Turkish with a strict family and about to get married, I'd say it's highly likely he will want nothing to do with it either way, whether you abort or not.
However having done single motherhood once with my DD, whose father was and still is involved, loves her, always paid maintenance, lots of contact, great dad - I personally couldn't purposefully bring a child into a situation that would be lacking those things. It's hard enough with the rejection, that you and possibly (through no fault of your own) the child would feel.
That is just my opinion though, the choice is entirely yours and a very personal thing. Only you can know if you really want the baby enough to be able to handle the extra horrible bits of no contact etc on top of single motherhood. I know many have found themselves in sort of this situation when the father has just upped and left and dodged all contact and the CSA etc out of the blue - so they didn't know it was coming and they handle it perfectly well.
Whatever you decide - good luck and all the best, and a big unmumsnetty hug!
