Okay so idk where to start we were dating for 2 years (start of COVID) moved in together bc my parents kicked me out. I had a few jobs here and there but nothing lasted longer then a month or so bc of my back. We were engaged for the last year of our relationship (making it 3 years total.) Not sure if I should try to get her back or not. I've had a new job for like 3 months now. (Broken up for about 5 now) idk I'm scared to ask her out to dinner and hear her say "sorry I found someone else or sorry you had your chance. We were best friends before the Break up. I ditched all my friends (bc they were assholes) so she was the only one I had for a while. Should I try has it been too long? I need help.....to quote bill from king of the hill "I'm so depressed I can't even blink"

(I stopped drinking and smoking weed. She had a problem with my weed smoking so I started with that after the break up)
