Is it okay I cheated and don't feel bad about it?
Is there a reason for cheating?
I don't know why I felt like doing it.
No matter what your reasons are, it's wrong to cheat on someone. You should break up if you don't like them anymore instead of cheating.
I don't care about that. It feels good.
Something is wrong with you if you don't feel remorseful after cheating on someone. How would you feel if someone cheated on you on purpose? You won't find any real love if you aren't capable of empathy.
