Wild guess but here goes. Concidering you have givn up your fair share for her, it dosnt seem to be working both ways. They say men are players well woman are just as bad, she has been keeping in contact with this other male for 1 reason, she is infactuated by him.
This is clear if she broke a promise it will happen again and again. But note she does love no doubt about that, she is infactuated so much by this person she will remain in contact with him let be txting or email. They will stay intouch disgreetly.
She's in college. There is so much out there for her. You really think she's going to stay in a committed relationship and waste the best years of her life?
The same goes for you. Who brings a girlfriend to college? Go out and have some fun.
This behind your back texting WILL NOT GO AWAY. In fact it'll get worse and worse. Your best bet is to let her go before you get seriously hurt and get sent into a tailspin of depression.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
