My boyfriend has major trust issues not stemmed from myself but past relationships. He's been single for four years before me and thinks I'm out to cheat on him. I do everything I possibly can. I cook every night plan ALL of our date /outings try to keep things fun. I give him passwords without him having to ask. I've changed my phone number without him asking just so past men wouldn't randomly contact me.  Lastnight I was texting and old male coworker catching up, I am new the my city still and was asking about a nice view and he suggested some. My boyfriend got jealous called me every name in the book and slammed me into the mirror. I know what you'll say, leave him. But he broke up with me and even though I know it's for the best I feel like shit. I could really use some words of encouragement.
