What's with these chicks?

[Wormwood]

So a couple of years ago, I started to get a little involved with this HOT girl I worked with. Not too far in, I found out she had a boyfriend, so I played the nice guy and backed off. She has since left, and now the girl who replaced her has caught my eye. She has a kid, and I have never dated a chick with a kid before, but she's hot and cool so I asked her out and she said yes. I then find out through the work grapevine that she has a boyfriend too. What's with these chicks, and how do you think I should proceed? [img]/images/graemlins/mad.gif[/img]
