I thought the situation sounded familiar, and then you mentioned that you'd made a thread on it, and I remembered that I chimed in on it... sometimes I hate being right...

Hey man, I believe in love as well. Very much so. But, no matter how much love you have, there are others out there that will evoke the same love from you, and you from them. I know you don't think so now, and don't want to admit it/think it, but there are other women with whom you can have a great, lasting reltionship.
Cheating is bad enough. Then confronted, she still didn't give it all up, you had to dig more. Completely unforgivable, in my book. Move on to someone who won't take you for granted like that, and keep you on the back burner so she can have her "fun youthful college experience" while having something to fall back on. Shitty man, i'm sorry, but there's nothing here to save.
