How to proceed? I sleep with a married man, none of us is obliged to each other, but I am jealous of the other, should I ask him directly about his intentions in her direction?

Are you jealous? Lol, yes, in this situation, I'm sorry, you are a simple gimmick, which cannot claim to be something more, because you are already destroying people's relationships. So you can shove your possessiveness away :)

How old are you? eighteen? It feels like you are living in a magical world. Stop it, otherwise only misfortunes await you. Sleep with a married person, okay, moral aside - nobody is perfect. Does he rape you or do you go to bed with him? If you yourself - that is, consent. You agree to have sex with him. All. Accept this, do not hope that he will leave his wife and come to you. He has two women with whom you can fuck + comfort multiplied by two, food multiplied by two, understanding multiplied by two - this is an awesome comfort zone, you don't even think that he will leave it. This will happen only if one of you is already completely unbearable. And most likely you.

Usually men whom they love live with, and not only sleep ...

Your jealousy is very strange - you knew in advance that the person is married, this implies a certain relationship.

You either accept this fact or not - if you go for such a relationship, then accept it, otherwise masochism turns out :-)))

You can ask directly, is it the same direct answer?
