Am I wrong for wanting to keep my baby?

My bf has been wanting a baby for a while now, he’s been trying to get me pregnant since January, tracking my period/ovulation and consistently not pulling out. Telling me he wants a family and so much more. Well it finally happened. I’m pregnant and now he’s telling me he doesn’t want it.. he goes back and forth, one day he wants a family, this & that and then the next day he’s flipping out.. I want to keep my baby, am I wrong for that? He also keeps saying, “if you want to keep it, just keep it, I’ll be there for the baby” then it turns into “I don’t want it”. I feel so silly for letting him get into my head and trick me like this..
