<human>: So I met this guy and we've chatting for about a month or so now. He mentioned before he was in a sour relationship but I misheard him and it never crossed my mind. We talk about relationships and feelings and other things exclusively. He even confided to me that he never has the guts to leave the person he's with and ends up staying in them for a long time until they do the breaking up. (I guess that was a sign I didn't catch until now.)

The entire time we flirt and joke around, I never once realized that perhaps I should even ask if he was taken. He confided in liking me and I kept trying to push where we were further. Earlier today he said he couldn't really do anything because he was in a bad relationship at the moment. It finally hit me that oh, he has a girlfriend. And this whole time we've been flirting and making jokes and talking on the phone and texting all the time. I feel bad for flirting back when he's had an SO the entire time but I never realized.

 I'm not sure how to go about this.  Of course I still have feelings for him but I'm wondering if I should even push a relationship with us after he decides to leave his SO atm. A friend said I could still like him, but in a patient way, because even if he leaves his SO there's always the worry of a rebound relationship which isn't healthy.

Provide a brief overview of the text.
<bot>: I have feelings for a guy and he feels the same but he's in a bad relationship and is afraid to leave it and I'm not sure how to go about it.
