A married man told me that he was looking at the Are You Interested feature on facebook. Why would he do this?

[Amarante]

He told me he might get a divorce and remarry (looking for potential mates). He said he might get married again.

His brother told him to do it.
He doesn't know for sure.

Wonders how people can be married for 50 years. He says won't they get sick of each other.
I am afraid of other people's safety.

He tells me stuff when I ask him about other things (school, work).

Just curious is all, not of my concern.

I am no longer in touch with him, just wondering what was going on.

It's none of my business if he gets a divorce or not, he is just confused about what he wants.
I don't know the answer and was asking him on facebook.

I am not interested in him at all. He was interested in me it seems, so had to drop him on facebook (getting very weird).

He's in his 40's and I guess has been talking to his brother about his life.

He says he would but yeah right.

Just curious about things and bored, so ask these questions and others as well. So I know what was going on.
It happened three times.
I get tired from working and he has a high sex drive (he wants it all the time) and he has told me that he thinks about it while he is working. He keeps bugging me about it all the time.
Not sure how to stop it.
Usually I am asleep when he comes home.
I guess he is bored being around me and wants something exciting.
very confused person
