Getting past first relationship complicated
So I've been dating a girl for nearly a year and a half now but ever since she has involved herself with other guys we have broke up and gotten back together. We still are in high school by the way. So the first time she went to a party and got home at 5 in the morning. And this was right after she told me I could give her my full trust. I broke up with her then she immediately went to another party with this guy in frustration. The break up was bad. We ended getting back together. So like I said we have broken up many times, and every time we do I've acknowledged our relationship and would stay away from girls but I still loved her and I couldn't stand her being with other guys. So every time we would break up, we would get back together soon, two weeks max.
Our last break up has been the one where I think I lost her forever. We have probably 3 months where we could be together but when school ends I'm leaving Montana and she is staying for school. So I know we couldn't do a long term relationship anyway. Now that we aren't together she isn't in a relationship but she is definitely putting herself out their making contact with 4 other guys. I've never during our breaks ups been with another girl or hung out with them but I have talked to 2 girls during our whole relationship break up moments. So I'm not innocent but I haven't done anything with anyone or just talked because after being with someone for so long I don't know how to be by myself so this last break up, she had been getting close to one of my friends who had just recently been dumped by his girlfriend.
The girlfriend noticed that her ex and my ex had been getting close so when after we had gotten back together, I wanted to make sure that this other guy and his ex wouldn't interfere in our relationship so I talked with the guy respectfully and the girlfriend respectfully but the difference is that I talked to him during school and her out of school. During my talk with this girl I had a good time but I still didn't want anything to do with her since I'm loyal to who ever I'm with, I've never talked to any other girl like that or hung out with another girl who I saw like that during any point in my relationship.
Ok so anyway, now this last time she broke up with me because we got into a fight just because she didn't want to be fair about something and she ended thing because I said its stupid how she over reacted to something she caused but then she tried to get back and I said no because of school and moving.Now I've decided to talk to the same girl I talked with after 2 weeks of the break up. I do admit I still have feelings for my ex but I know I must move on. But now I'm getting the feeling I'm the bad guy in this because I'm looking for someone else already. My ex started probably the day after the break up but she admitted she loved me. Now that I have a connection with this girl, I do know that she has a rough past with guys and just got over a long lasting relationship with a guy she's always loved. She likes me and I like her but now that people have seen us, lot of people are talking bad about me saying how can I do that already.
So I'm stuck between the situation of staying and risking a hurtful future because I could get played by this girl; maybe killing my reputation since most people see me as a good guy but I've heard people who are good friends talk bad about me already, and leaving myself alone completely because past girlfriend ruined my relationship with many of my friends plus other of my friends feel like I'm awful for looking forward to another girl, but I mean prom is coming up soon too and I want this prom be good and have a date.
On the other side, If I left this girl I wouldn't have a good chance of getting back with my ex but it's not so much the feeling of jealousy I feel with my ex whereas it's more lonely. I do love my ex but I thought I would be good to release myself from here since I'm leaving soon. What do I do? I don't feel right about maybe rushing but I'm afraid I would lose everything I have with this relationship if it didn't work out.
