been there done that and realised after wrecking a friendship that it's just because i cared about that person so much that i just didn't want them to get hurt. it's called being overprotective, and that's it.

i'm a jealous person too and when i see my close mates being close with their other mates i feel like crying. if you wanna talk about it, PM me.
(are you in england? i noticed the time you wrote in your post (2.18am) was ten mins before you sent the post (2.28am) and it probably woulda taken about ten mins to type that...)
