<human>: Backstory: I started to be friends with this guy right after his ex cheated on him and left him with some guy she met online. It recently didn't end well and now she's back in the area to live with her family. 

Right now we're technically just friends, but I'm finding myself to be more and more into him. We go out to movies and dinner, hang out all the time, he's meeting my parents, he drove me to the hospital at 5 am, massages, etc. I would love to start dating him, but even though he has not seen his ex for over a year when she left, they are technically still married. He says it's mainly to do with money/she doesn't want to go the easy route, but it still makes me uncomfortable that they broke up so long ago yet still haven't gotten officially divorced. 

It's not that I think he wants to stay with her (the animosity is pretty clear there) but rather that I would feel better if she didn't have any ties to him or any leverage over him. He has said he doesn't consider himself married at all and while I know it's just a piece of paper, it still makes me feel uncomfortable that this divorce is taking so long. Am I being ridiculous here?

Could you distill the essence of the text into 1-3 sentences?
<bot>: want to start dating my friend, the fact that he's still legally married is giving me pause. Am I overthinking this?
