Not sure who the father is

Selyna
So I am 6 months pregnant my boyfriend and I have been together 7 months. I got pregnant between dec 6-14. He was working in Texas and I would drive up every weekend to go and see him. But I had a friend that I would hang out with back home. I was still talking to him during this time but didn't hang out with him. My boyfriend thinks the baby is the other guys and I know it's my boyfriends. What should I do? I really need yalls advice. No mean comments please.
