Confused with ex

Me and my girlfriend broke up this summer.She is 10 years younger than me.I was her first and I broke up with her.Even though we started off both very deeply in love , i ended up in some point where i thought i did not have the same feelings for her than i had in the start and that it was the right thing to break up. In addition to that , we did not share the same lifestyle , even though we had a lot of fun the times we were together, we shared some same interests and way of thinking and shared some unique times together throughtout the relationship. After we broke up , she went after me and tried to win me back . I did not believe at that time that it was right to go back , but i stayed around , and we continued seeing each other frequently but , without the label ''in a relationship '' . Not like an open relationship but something in the middle , can't really explain it. We had feelings for each other but I just could not see that I still loved her .And that propably I just needed some time for the relationship to cool off and not rush and break up with her. As time passed , i started to change my thoughts and started to think that i was wrong . By the time i thought it was the right thing to get back with her , she had already met someone else and started going out with him.I went after her , tried to win her back with every way i could but with no positive results. Now she seems convinced that it is kind of too late . She is of the oppinion that, i should have done something sooner, even though she continues to tell me how she misses me sometimes , and that she still loves me. She also thinks that she is afraid of being back with me again because she was so broken hearted, and might still be. And that she thinks that her ‘’new life ‘’ with her friends and this new guy is the life that fits her . She also believes that , in some point in the future we will be back together again . I don’t know if I can believe that . I do have feelings for her but I think the relationship has ended for good. I want her back though. But I just don’t know if I must leave it be and let time show what will happen or, if I have to continue somehow and try to find ways of getting back with her , even though I think I did everything I could .

Sounds like you both are still very young and not totally sure and what you want. If she is in a relationship, I would respect it and leave her alone. Otherwise it's a possibility you two will start hooking up when she's seeing this guy. Let her go and figure out if that guy is for her. If it's not, she'll break up with him and go back to. Please respect their relationship and in the meantime I would keep my options open.
