I've had my trust issues since last summer but I think I've worked through them and as to when do you trust someone I'll just say sometimes you have to take a chance on her/him.
What your describing has happened a few times on this site in the time I've been here. 2 ppl get together and announce it on the forums and BANG someone else will try to come between them.
As to why it could be alot of reasons but to me they just want others to feel as low as the do them selves.
