So my boyfriend is a sweetheart, and I know he would never cheat on me. My problem is that he's been texting this one girl that he knows I don't like (she tried to get him to cheat on me, and he wouldn't have it). She's kind of a slut, and everyone knows it (she flaunts it, so it's not like I'm being mean about it). But she has a lot of family problems, and my boyfriend is nice to everyone and likes to help people out. I don't know exactly what the family problems are, but it still bothers me that they've been texting a lot. He even deletes all of their messages and won't let me read them because he promised her that he wouldn't tell anyone the problems. What do I do? I really don't like them talking.

So you know he wouldn't cheat on you, do you? How do you know this?

He's "helping" this girl in some way and is deleting messages....that tells me something.
