Why would a girl exchange numbers with a married man?

Anonymous
I started dating a girl a few months back, she works as a bartender and has a lot of customers she meets at the bar. One guy specifically is a flirty outgoing guy. He is married and has a kid. He admits to not having a great relationship with his wife. He definitely comes off as a guy that cheats on his wife.

My girlfriend has his number in her phone and he texts her from time to time (that I know of)

This doesn't sit well with me. She says she loves me and I am what she wants, but then why would she associate with a guy who comes off as a douche bag.

The guy also has made comments about me while I wasn't around at the bar, calling me gay and blah blah blah. My girlfriend has told me about this. She still texts him.
