I am dating a 22 year old guy, I am 19 and he said that he was going to have a baby with his girlfriend but then he discovered that she cheated on him so he left her. He said that she did not admit that she cheated on him but he knows that he went with her 2 weeks before the baby was formed according to the tests. When I told him that he still can't be sure, he said that she still can't put charges on him if a specific amount of time passes after the baby is born. That worried me because if it is his child it is his child, charges or no charges!
However, he treated me right till now and told me to tell my parents about him and to start an official relationship with him but he want me to go to his apartment (rather than to meet his parents first). I don't know what I should do, do you think this is the type of guy I should run away from? Because he does give some mixed signs I guess.

He sounds like a loser really. And I also think that the fact that you're asking this means you already know the answer.
