Help!

I'm 5 weeks and 2 days pregnant, me and the father are currently in an 'open relationship' it's been going on for two years only because he doesn't want a relationship because he can't commit and isn't ready to give up the single life even tho neither of us have been near other people in the last 6 months. That is one messed up situation and now I'm pregnant I'm 26 years old and considering bringing the baby up by myself as he is not ready and really wants me to get an abortion I don't know what's best I keep crying and I'm in a real state over what to do!? Is it possible to be a single mum? Would I cope?
