Hi I'm crystal I have been going out with my boyfriend for 1 year 7 months but I went away with my family for a week and when I got bak he told me he went to his ex girlfriend house he said nothing happened but I was texting his ex girlfriend and she said they had sex but I don't know if he did or didn't he told me he didn't but his ex girlfriend loves him and she hates me for being with him but I don't know if he cheated on me or not so please help me.:(

Well sounds to me like she's just lying to you trying to make you leave him.

I mean just trust him if he said he didn't, then maybe he didn't. If he's going to cheat he will cheat. There really isn't anything you can do to find out, all you going to do if you keep nagging him about it is push him away. Do you think he cheated on you? If not then just leave it, trust him and move on.

All comes down to whether you trust him.

This will not be the last time you hear something like this, it's a common thing - and especially given that this other girl hates you..

If you have such a problem with him going to see his ex, tell him that too..
