I need help

Hey girls..

I’m having a hard time, and many people may not see it as hard.. but it’s killing me. My entire life I have dated nothing but cheaters and abusive men.. now I believe I am dating an amazing man.. we met in college and have been together 24/7 for 7 months.. he now has a job as a car salesman.. and he doesn’t even message me, but even during lunch. He is surrounded by hot receptionist and other female salesman.. and i am so scared.. but I know when I bombard him with questions when he gets home it just pushes him away.. even last night he told me he doesn’t want to wear his promise ring... I’m so scared.. but I feel like I can’t keep living in fear because of my past... how do I get over my fears? What do you girls do to get your mind off of this..

Please help
