The green-eyed monster

I met this person online a little over a year ago. We met via an online game where we each roleplay with different characters. Since then we started chatting on an im and we're practically inseparable now. I greatly enjoy having him for a best friend, the problem is he's a very jealous person. I noticed it near the beginning when a mutual friend tried to convince me to join another game with them. However I disregarded it. Now things have gotten more complicated. Something major happened a few months prior and he won't tell me what it is. All I know is that it's jealousy related and game related. He gets really angry about it sometimes, even now. It's driving me nuts that I don't know and if it is jealousy related he has no reason to be. I spend most of my time with him, not just in game. I don't know what to do. I don't want to lose a best friend and I don't want him getting mad whenever a used-to-be-mutual friend talks to me either. What should I do? Is this all in my head? He said some things tonight... that were so terrible. Like if anything went awry between us, he would turn his back on me until I completely disappeared from his world. And that he's territorial and when someone steps on his turf the claws come out. It kind of made me uncomfortable.

He sounds like a really possessive person, which isn't healthy in any kind of relationship. Have you ever met each other outside the online game? If he trusts and respects you, surely he should tell you what the problem is and why there is now awkwardness in your friendship?

No, we haven't met in person but we did talk on the phone once. That's what I think too. The reason I was given for not telling me is that it involves other people. Sometimes he tells me that he "might" tell me sometime which I find equally irritating. Either do it or don't.. but there's no need for the tease. I think he might have told another friend that it involves but that friend won't tell me either. She just tells me that if it is the same thing, it's something selfish and stupid and that it's not my fault.. and not to worry about it. But not knowing is worse. Plus the guy has also told me that it's a stupid thing but that he can't help feeling mad about it.

sorry to tell you but this guy is crazy. im glad you haven't met up and please don't if you are all ready feeling uneasy about this person then listen to your gut. you see him as a best friend what does he see you as? please tread carefully.

Yeah, I was sort of afraid that might be the response. He said I was a good friend and he is in a committed relationship to someone else. I think it's only a friend thing you can be overly possessive of friends too but I can see your point. I used to have another best friend that was overly possessive .. and that was a she. She thankfully has settled down some in recent years but not until after a nasty blow up. We still talk now and things seem normal again
