Pregnancy with fwb

Hi everyone.

I'm in a bit off a mess today because last month I met a guy who I've been doing sexual stuff with. We have had sex once 2 weeks and 1 day ago and now I have got a positive pregnancy test. The guy has a girlfriend who he plans to move and live with next year even though he was cheating on her with me!! Anyway I told him about the test & showed him photos. He isn't happy at all and wants me to get an abortion just to save his own ass. He knows if I keep the child it will come out he has been sleeping with me behind his girlfriend's back. I regret having sex with on every level now that pregnancy is in the question. Very stupidly we didn't use a condom and I don't know why! I'm 16 he's 25 and he was my first. Please no negativity because I'm already such a mess and I don't know what to do. My family are supportive in this also! 😥❤
