Do you do this or know a guy that does this?
Do they really like the girl or is it just to be with her no strings attached?

Some men will do this because they are womanizers and don't really care if the woman is attached or not. And, yes, some will feel that if a woman is married or in a serious relationship, she won't be able to put demands on them for a relationship and that suits them fine.
Others may do it in a one-off situation because they believe the girl is unhappy in her relationship and they want to be her white knight. Those deals usually end with the guy feeling pretty crummy because the girl either stays or goes back to the jerk she is with or the girl is just a serial cheater looking for her next target.
Overall a guy who pursues a girl who is taken should not be trusted.2
