i just got dumped by my girl was with her for a year and a half. I was being overly jelous and did not trust her. She got sick of it. I want to stop being jelous but its so hard.She cant even be with a guy friend and i would get jelous. But now that we are not together there are lots of guys at her school trying to talk to her she says she wants to be alone and is not interested but i still cant stop thinking they are gonna grab her before i fix this jelousy thing.I really want to be with this girl she also told me she left me because of my jelousy.How do i fix this and prove i can change
