Knowing all is not right. Lets go back in time

I'd like to think I'm pretty good on picking up on the slightest changes in someone and do notice the smallest of things no matter how relevant or irrelevant they are. Lets switch back in time a few months, here I was meeting a man called George on a website called manhunt. Seemed a really nice guy and we chatted a bit before bang the news comes out he is in a relationship, but not happy etc etc, you know the story. We meet anyway and not before long that relationship is over and we are in a relationship and things seem ok but then I notice things that ya know are just not right one been his biggest thing always taking his phone to the toilet, shower well basically when ever he moved. Sounds strange? I thought so as did I find strange his slight behaviour changes and his constant contradictions in things he said and did

Move forward 3 months later I found he had re opened his manhunt account after he had closed it, which stated single and looking for what ever and I mentioned this to him to be given some pathetic story about it and how it boosts his confidence.

So skip forward no more than 2 weeks later and we were over, the story of feelings for his ex, not really fair on me etc etc we shall remain friends. So I attempt this and we go the cinema but all other meets arranged were cancelled the latest one because he was with a guy and you can guess where from, manhunt. Oh the story thickens they became friends on facebook the day we broke up on Sat 25th September. So here is the guy telling me not interested in anyone and that manhunt was to boost his confidence etc. Yet the day he had arranged to meet this person (which I suspect is not the first meet) was the day he arranged to see me but failed to even tell me he was not bothering so this is when I decided to do a little digging around and finally things began to click in place. It seems to me it's a circle of repeat but as yet I don't know for sure it's just my conclusion. I have concluded he gets in a relationships from men he meets on the net but when needing someone else he finds someone else and when he knows it could go somewhere tells that person (the new person) he is in a relationship before finally making excuses to call a day on the current one and getting with the new one

I suspected cheating or something fishy was going on when we were together, and even mentioned it to him and that I suspected cheating but was reassured not. but I know he has in the last relationship and should have followed my gut instinct on this one. So to that note I've called a day on the friendship if you could even call it that in the first place. Half the time he just ignored my texts anyway sometimes till the day after. A shame really and a very lonely place he will end up in the future.
