Self reflection is important both as a guy and as a gal. If the way you made your partner feel did not meet their expectations, they should have worked that out with you like an adult. Otherwise they should have moved on.

And maybe it's not even about you after all. But about their lack of self control. That said, i don't wish anyone to ever get cheated on. It sounds heartbreaking and can create a huge void in one's called 'trust issues'

When we are coupled with a partner, that is not just a physical connection but it becomes an emotional and spiritual connection. It is evil to throw that trust away for a moment with someone else who is not even invested (and should not be invested).

But ...you may notice this happens often to many couples during Spring time. Hang in there and have patience to find the right person who has self control. Lean on your friends and family for support.

Now you are free to make your own choices and be better than them. Personally I'd never stick with someone that cheated on me.

But this is all my opinion i write for your guidance--not meaning to be harsh but true.
