[hurtandhumiliated]

My boyfriend and i have been together for 5 years in april. We have had problems in the past regarding him lying over the dumbest shit (e.g. hanging out with a certain friend of his who is absolute scum or boldface lying to me about some lost money he found-i was going to pay him back for the misplaced $100 bill and he STILL didn't fess up). I am recooperating from H1N1 and a few nights ago i discovered that he has been texting another girl. She is in 2 of his soon-to-be-ending grad courses. He said that he knew she was into him and that he used this to his advantage because she is an overachiever, he used her for study guides and, let's say, an 'educational edge'. He swears it never went further than that.
Jeremy is my one and only. we met when i was 20. i had/have never been with another man, nor have i ever even thought about it. he just led her on to get extra help with the course.

I dont know what to do, I love him so much- but i have never hated anyone this much before either. I feel so broken and lost. I feel like I am dying.
