How to get her back when she lost interest

I was with this girl 15 months it started off a cool dude with control and balance in relationship. I was a lil bad when it came to emotions but I got them fixed when I went to navy. We didn’t talk for 5 months because I got injured and after three she dated a guy cheated and he dogged her etc. I forgave her because I was kinda mean and hard on her and she was really great. She couldn’t forgive herself so we argued about that than it was about me getting myself together(I had no job) than she stressed out about school and moving etc. while time I tried helping and listening but it was pointless because that’s what woman do lol. We had some conflicts because he single female friend always wanted to party and stuff. Long story short she left me two weeks ago said she lost interest see no future with me don’t love me hates me and don’t trust me anymore. She says she been loosing interest for months and just wants to be single and alone and selfish. Btw we both in early 20s. I reacted of course and I honestly had 2 beta moments that were embarrassing than I agreed to the break up. That caused her to contact me 3 more times 2 to start something and 1 checking up on me(there was a bad storm). She than left to another city but never saw me before she left. It’s been two weeks since than and I just seen two post talking bad about a ex(me). One was a joking picture another was a rant about me bashing her trying to get her back(she said beg lol) how I changed how she viewed things caused her stress and how happy she has been and how she isn’t pretending anymore. I love this crazy girl still sadly and have been focusing on me because I didn’t give her stability (no job not in college or service) which caused me to be to available and caused her to loose interest. What’s the best move? Continue no contact? Or light contact? Btw her b day in couple weeks to
