I think my boyfriend cheated on me while I was on vacation in Jamaica for the month of Febuary HELP!

So I went to Jamaica for the whole month of February to visit my step-dad's family, while I was gone me and him were texting and we got into a couple of fights, when I got home I heard him and my friend were touching each other while waiting for the bus, I thought "she's my friend I dont think she would want him like that and even if she would I dont think she would try to make him cheat". Next Monday I went to school, she couldnt even look me, so I thought maybe she thinks im mad at her and wont want to listen to what she has to say, This week at school she told a couple of people she was pregnant and everyone asked her boyfriend if they had sex yet and he said no he wanted to wait. That got me thinking .. what if she is pregnant and what if its with my boyfriend ..
what do I do ?

if it's your boyfriend, break up with him and start a better life and move on. if not, don't trust to the rumors if you have trust to your boyfriend. maybe you should talk to him or to your friend for confirmation. always remember that a strong faith is not weak to gossips.

Ask your boyfriend for his side of the story, and decide if you want to wait to see how this girl's baby drama plays itself out. Also think about if there are other valid reasons to end the relationship. All of that should tell you your next move.

If this is going to be nine months of worry and aggravation, I say jump ship.
