That has gotta be the most spineless, gutless and heartless ways that a guy could ever dump a woman. In all honesty, I would'nt throw away a 4 year relationship even if my girlfriend had f*cked her boss or sucked him off in the toilets. But I guess thats just me, we all make mistakes, and we should all be able to forgive even if forgetting could be a lot more difficult. Many relationships survive unfaithfulness either by one of both partners. And IMO if she had to resort to sex with her boss, then she obviously was'nt getting what she needed at home, so the guy only has himself to blame. What a spineless piece of **** he is.
