I think my girlfriend wants to break up
I'm new to this site so I really don't know where to start... I'm a 15 year old boy, I have been dating my girlfriend for 7months and 22days now. She is my first girlfriend as I'm her third boyfriend. I spoil her a lot, I'm the only boyfriend who has been approved by her family members. I love her very much and I would give the world up just to be with her as I have put up with a lot of crap that I didn't need just from her family members alone(An example was I had to bus to her house at 9pm, she lives about a 45minute bus ride away and had to bus home around 1am in the morning because her parents wanted to have a "talk" about our relationship). We broke up once before, about 3 months into the relationship. When we first broke up it was because of the constant pain of her being a big flirt behind my back(I found out she was a big flirt around 2 months in the relationship as she promised to stop), shortly afew days after the breakup I realised I love her and I wanted her back. As it took me a month to get her back, during the breakup I skipped afew classes to visit her(as she went to a different school), called her a lot, and we were constantly contacting each other. Right when I gave up she asked me for a second chance. Ever since then we have been very happy and there have been afew jokes about our future/marriage. Such as "When we get married lets name our first child Raine". Just recently we got into a fight that lasted 4 days while it started with her being a flirt behind my back again,cause a fight and leaving me with nothing but anger for a day, the second day came and I forgave her and tried to makeup but she shoved that into my face leaving me with anger once again and leading us into a bigger fight, the third day came around and the same thing happened as day two, and the same on the fourth. But on the fourth day she suggested breaking up saying things like "but because i respect myself.. i wnat the best for myself ... and its the same for you.." as this fight was the worse fight we ever had... But at the end of the fight we worked things out and we are still together but I'm still hurt and I'm pretty sure she is too. But now I'm confused about why she is still with me. I keep asking questions like "Why is she still with me? Is she with me out of pity? Does she still intend to stay together?". As I'm really frustrated, my tears flow endlessly, and I cannot sleep as it is 3am coming up with two unit exams tomorrow. This pain knowing that she wants to breakup or at least tried to break up is really unbearable.
Is there anyway to save this relationship?
What should I do?
Please Help... Any answer would be great and really appreciated...
Thank You
