i don't think if i can judge you a good or a bad guy....but what i can definitely tell you is what you are doing is wrong. Also what I can tell you for sure is the consequence of this affair. I don't know if their husband and boyfriends know about this adultery and how will they react to this. I don't know if they will be coming with gun to kill you. But whether they kill you or not, your own emotional guilt will kill and it will be slow and painful. You have now seen, known and felt how some women can be so unfaithful. So if in future if you accept a relationship and you really love her, you will always have this fear if she is cheating with you in the same way as these girls are and you will live with this feeling for forever. You will be happy as long as you are not in love, if in case you really fall in love, it will be painful after that moment.
