I can't say I've had "extreme" jealousy, but once, when I did have a friend, he was pretty much my only friend, but he spent time with his cousins fairly frequently, and I used to resent it because they had several friends, but he was my only friend. I felt they were infringing on my "friend time" by taking up so much of his.

Did you control the jealousy, or speak to him about it? As for me, i'd control it... most of the time. Sometimes i'd fly a bit off the handle and start asking endless questions about the dude.
