So I am being very jealous about my bf and a particular event he is attending with his ex that involves a few nights away. I really do not think he is interested in her. I do not trust her. There have been a couple of half truths and lies which have now catapulted me into a huge jealous disgusting mess. My ex cheated and lied, also abusive. So I really do own that I have an issue but to be honest that’s not helping. What can I do...?
