I'm going through something similar, but my boyfriend continually plays Xbox with this girl who recently split up with her ex....who also played Xbox with him. And I seen she sent him message with kisses on it, and I flipped. Nut it's his lack of spending time with me but willing to laugh, joke and spend hours every day with her has caused me to go crazy and I mean I have gone proper crazy on him.....I'm convinced they are up to something. He swears he isn't but I just can't shake it. But I'm trying to remember he lives with me. It's only my crazy brain that has fabricated all these things they have been doing behind my back. It's tough to shake those feelings and thoughts. I feel your pain just now, everytime I bring it up he tells,me to deal with my own stuff and he's going to play with her anyway.....that just sets me off again.....it's horrible keeping it all inside. Hope you find peace soon. My thoughts are with you x
