By "out of mutual convenience" I mean she doesn't want to have to move back in with her father and neither of us really want to pay for a whole apartment ourselves. And no, I'm not taking advantage of her. I do most of the shopping and pretty much anything else that has to be done outside the apartment since she hates leaving the apartment. We both do the cooking. Also, we get along great.

I wish that she wanted to work it out and get back together... but she clearly doesn't really or she would agree to work on the issues that she knows are the reasons I broke up with her. If she actually wanted me back, it wouldn't be that hard for her to achieve.

Instead she seems to be happy living in a limbo state somewhere in between a relationship and roommates. She knows I am seeing other women but I don't tell her about it specifically because she gets upset. And no I don't take any girls to my place. That would definitely be awkward. If I want to do anything with another woman, it's usually her place or a motel (or often a DVD Room).
