<human>: Can you give me a shortened version of the text?

I recently met a guy that I'm interested in, but he has a girlfriend. I get the feeling he's into me as well and we flirt a little. I guess I can't be sure, so I tend to stay at a distance while still keeping a toe in the door in the event that he may become available in the future. I'm very careful about not crossing any boundaries.

One night we're out with friends (sans the GF) I asked him what his GF was up to and it turned into a convo about how unsatisfied he is in the relationship. When I asked why they were still dating he said that she was his safety net. I didn't push any further because I didn't feel like it was my place, but on the inside I was just screaming at him. WHY?! He also didn't seem to have any intentions of breaking up with her anytime soon.

Why did he tell me this? Is it just a matter of time until they break up? If they do, would it be bad if I stepped in? Am I reading too much into it? Where to go from here? WTF?
<bot>: Guy I'm interested in tells me his girlfriend is just his safety net. Do I need to run far, far away?!
