How do I tell if my boyfriend is cheating?

My boyfriend's name is Brian and his cousin's girlfriend Tiffany who is also my friend told me that this chick came up to her and told her that she might be pregnant with Brian's baby. And has been cheating on me. I don't know whats going on. I talked...

to Brian about it and he said that he hasn't and he wouldn't and that he loves me. But I don't know why someone would make up something like that. I know a lot of people don't want me and him going out because so many people like him so I don't know if she is making everything up or anything. But I don't know what to do. Can someone help me please...

You need to contact this girl! try finding out who she is off Tiffany and try talking to her to get the facts!

Dear pyrochick85,
You obviously have some doubt that he is not cheating. You've asked him and he said no but you don't believe him. Either you trust him or you don't...So you don't trust him then now's the time to evaluate your relationship with him. Is this the person you wish to make a life long commitment with? If you don't trust him now what future do you have with him? Take a long look; sounds like you already are seeing problems.
Sue...good luck

Ask your friend Tiffany who the girl is that told her that! You need to talk to her and see what she says about it. Your boyfriend could be lying to you, or your friend. Its hard to tell until you get more info.

Do not deal with this question now. If the baby is Brian's, you will know it soon, because he will be a father. And say that Brian does not cheated on you, he cheated on the other girl. In the really young age, as you are, this happens more frequently than happened earlier, when lovers where older.
