If I may step onto a soap box for a few minutes here, and tirade against this self-righteous strumpet...
Tomi Stark, if ever you find this post on this site, lend me your spray-tanned, pierced ears. If a man cheats on you, simply leave. Don't try to reconcile with him, as you had your chance, and you spat in his face. Don't punish him, because you're clearly the one at fault for neglecting him. You did nothing but drain him of his money and time, and gave nothing back. No honesty, no intercourse, no affection, not even loyalty.
Given that men, specifically whoever you were dating at the time, are typically so deprived of affection of any kind, that even something as simple as a compliment would be enough to put him in a good mood for the rest of the day. It makes nothing but sense that he would rather seek comfort from another woman than continue to consort with this snake.
In short, Tomi, I guess you could say you lacked something that made him cheat... a lot of things, actually. Basically, don't be a conceited tramp, is what I'm saying.
Sincerely, an anonymous, disgruntled man from the internet.
