Emotional infidelity?

What would you do if someone cheated on you emotionally, but not physically? Would you stop dating or talking to them? Would you forgive them and move on? What would you do?

At that point I find an exit from the relationship. It's no longer viable, at best you're just existing together. The mood turns stale, the other person is mentally absent while physically being with you.

I mean that in the nicest way possible.

Unfortunately, most relationships are defined by emotions. If both persons are not in love then then isn't much reason for a relationship, might as well just be friends if anything. The only other reasons to stay in a relationship are financial or emotional dependence, convenience, or merely for the sake of raising children. It's best to be open with your partner about your feelings or lack of and hurt them less then by cheating or leaving without explanation.

I guess at that point you have to decide whether the person is worth the effort of trying to win back, or would it be better for both of you to just end it. Hmmmm, without realizing it, I went through this last year. A girl I went to see after knowing for years started falling for her ex again. She became less flirtatious and quiet. I could tell she just wasn't there anymore, and decided to end it.

I think it depends on whether or not my significant other's feelings towards me have changed for it to really bother me. I don't believe love is a zero sum game. As long as they still care about me the same way as before, our relationship is still good, and they don't act on it in the physical level, then I think their entitled to the privacy of their own thoughts. But that's just me probably hahahaa
