Married man mid 50’s

You have now posted this question 3 times. Didn't you like the other answers you received?

You shouldn't have to ask. You'd KNOW if he was receptive to your flirting.

Age is just a number, grow the $#@$ up.

Seriously it depends because of the current situation.
At work and your married I guess it would be no, because that is not the kind of family you have.
Beyond that on break I would say yes the attention would be applicable.

As you keep asking the same question again and again on different threads it's safe to assume you're quite needy and obsessive.

If he has any sense he will get as far away from you as possible.
