Relationship problem =[

I don't know what to do now. if I should stop talking to her for good.or try to deal with it. here some detail. me and this girl been off and on for like a years. ect. ect. found out monday she dating someone else. she basicly told me She didnt want me....

I can understand that and all. but she shoulda told me sooner. she had me believing we should have a real serious relationship. well that shatter my heart. When I thought things couldnt get worst. Her boyfriend is 17 and she 15. wtf you doing dating older boys like that.I believe that jerk only one want thing from her. I don't know what to do no more. I feel lost. sometime I even want to cry -.-. When I met her. She brighten my life up. made more cheerful and stuff. now all this BS is happening. am considering Just to stop talking to her forever. I don't know if that the best choice. Cause I Really love her. I don't know if there something else I can try to do. I feel like I already lost her. I just I don't know what to do now.I never been heart broken -.- . it seem like without her. I wont be able to fall in love again. Can someone give me some advice please. am at a dead end =[

well I can help you I have actually been in this situation... this guy I loved did the same thing... we stopped talked because he thought I was trying to break up his relationship... bc I was telling him she was cheating on him becahse she was. but anyways we stopped talked for almost a year and he found his way back on my door step telling me he was sorry and he should of listened to me... if you love her let her go if its ment to be she will come back... things have to get harder before they get easier. me and that guy are now good friends so maybe you should stop talking to her for a little while see what happen even thought it hurts. I hurt a lot but I learned to deal with it. I hope things get better you can message me if you ever want to talk.
