Is this cheating, would you forgive and can he be trusted?

Please help. I have been with my fiancé for 3 years, engaged and living together for one year. He plays this game on his iphone where people all over the world play it. He's been playing it for about 6 months and speaks to people in the game chat room about the game which I see because it's on the ipad. He has been speaking to a lady in Washington for 6 months only about the game which I know as I've seen it on the ipad. Anyway I was being nosey the other day and looked at it and the day before he spoke to her in appropriately sexual and said things like what would happen if he came to Washington. We live in the uk so I don't know what he was trying to prove. I confronted him and he said he was stupid had no intent and it was just a conversation that got out of hand. I kicked him out and he's back at his mums. He wants to save our relationship. Do you think this is actions of a cheat and he can't b trusted or do you think he was just stupid and I shouldn't end our relationship. Also i know this is no excuse but this happened the day he lost his job and we had a row and he said i didn't support him

I honestly don't know if I could trust him again. If my boyfriend done that to me I would break up with him. Anytime they do something like that it makes you wonder if they can be trusted in the future. Do you plan on marrying him or having children with him? If you find out he's cheating them would you want them in the middle of it? If you decide to stay with him I would suggest canceling. Or you could stay separate (but make it clear you're not going to be with anyone and expect him to do the same) and go to counseling together and see if you can work it out.

You asked this before. I answered it before. I will answer it again with a different thing for you to consider.
Look at all the questions on here from people whose *entire relationship* is electronic and yet they claim to be deeply in love before you say what your boyfriend did was not cheating. People have relationships that are entirely electronic and yet those relationships are as real to the people in them are yours is to you. So your boyfriend chatting up that girl was not just "nothing". It was real.
How do you FEEL about what he did and what it says about how he feels about you?
