Can't got threw with this pregnancy

So I'm only 6 weeks along and I find out my boyfriend and the father of my baby cheated on me this past Saturday. I love him more than anything but I can't bring a baby into this world in a broken family. He's done something like this before and I don't want to go threw it for the rest of my life. Should I go threw with it and be a single mom and raise the baby or should I not or should I give the baby up for adoption. I'm really heart broken at this moment😞😔💔
