EX and pain

[ekearsh537]

The whole story is the key to my pain. in August last year my ex broke up with me because she said i was unable to produce an intelligent convo(excuse). we get back to school and she tells me the break up was really hard for her and wish to talk, so we did and we would hook up and seem good but then she say lets just be friends(this repeated four times). then by December i told her i am done and not to talk to me again, so few weeks went by and i slept with my friends ex (so ashamed i hid it). then January came and my ex and i talked about our problems and we reconnected. then in April we had a huge fight and i had family problems so we broke up. Two days after we break up she slept with someone (bc she was drunk she says). then three weeks later we talk and become friends and that led to friends with benefits, then feelings came in and we were practically in love without a title. then in june my friend found out about me and his ex, so he called and told my ex everything. so weeks went by with me and my ex dancing around the problem and she would mention it or id wonder what we are. We had a huge fight when she told me she just doesnt want to be with anyone and not even me, so we didnt talk for a month. Then randomly when we got back to school she would send me text to try and get me to talk, one was guess whats on tv (the first movie i took her too). then we had an all day good text and later saw her at the bar, when she was all over me and kissing me, but she was drunk. the next day she came over with her friends to my new place, and we made breakfest. i then went back to her dorm to do laundry and just hang out, we then lifted together like old times. Then i saw her walking back to her dorm with another guy (after a party later that day). My blood was boiling and i was hurt. I told her how i felt and she would not talk to me face to face so had to send an email to her and she said just because i was nice to you doesnt mean i wanted to take you back eric. I decided to just not talk to her for awhile, but then heard she had hickies all over her neck. I am torn because i spent 2.5 years with her and i thought i would marry her. i am 22 yrs old though. so i am asking for advice on how to get her back back if possible. i actually changed and matured from this pain, but another part of me just wants this all to be done and over with. so can i get advice on both sides and decide from there? thank you
