Your right Quinn and you nailed it!, great advice. Dude, move on she just using you on top of that I believe she also has a mental disorder, not trying to be mean, but its possible she is Bipolar. I would suggest you let her know to seek help. Usually when someone is really depressed they can not make right choices and everything is a blurr, the norm would be she would stick with you but she wants to go and meet other men which seems she has a maniac phase also. I am not a doctor but I have seen this couple times with my friends and it always leads to that condition. DO NOT tell her she is Bipolar, let her go to the doc if she chooses and let her tell you what the doctor found. If that is the case bro, I am sorry for both, its not a great place to be cause in part its not her fault either her mind is not in the right place and is not capable to understand certain things. But if she can't love you regardless of her mental state, she is not for you. Plenty fish in the sea. YOu guys can still be friends but you would need break, distance to give your self time to heal and move on and then you can see the whole picture and remain friends and give her help with limits of course when she needs it without F*ckin up any new relationship you might have. ( jealousy) but I suspect she might going through a mental disorder and its gonna get worse as she age or doesn't get medicated. Sorry bro I hope I am wrong.
