Do you think my boyfriend is cheating on me with his ex

My boyfriend is in london with friends of his and his ex girlfriend went too and she still in love with him I hope hes not cheating on me with her and she keeps keeps telling me that I dont love him I told her that I love him and she still likes him

Shes probley going to try to get with him - whether he takes up the offer or not, who knows. Why did she go and you didn't? Hm... not good.

as long as you aren't smothering him, and continue to do what he says he won't cheat on you. But don't stop being self respecting.

wel if hes saing you dont love me
thats quite wierd as my ex did that to me and he played me soo be carefuly yer?

he didnt pay for it one of his friends did thats why I didnt go and his ex is still in love him what can I do about that and im scared he is cheating on me with her if I asked him if he did he wont tell me the truth

Has he given you any indication that he would cheat on you (with anyone)? You should trust him until he gives you a reason not to. If he does cheat with her, it will come out one way or another. If he hasn't done anything wrong and you ask him about it, you will come off looking like the psyco obsessive girlfriend.

he called me while he was drunk said that she wants to have sex with him and thats why I think he cheated on me because of that but I dont know if they did anything or not

If he told you, he probably doesn't feel guilty about the outcome.
