Search Results: he gets very jealous

A few years ago I had a coworker in another department ask me out on a date. Thought I hadn't dated in a while, might as well. She changed the plans from getting drinks to hanging out at her place. She gave hints she totally wanted to have sex, but also wouldn't shut up about her ex. I hadn't dated in a few years, so I was disappointed this was my first experience. Plus she still lived at home with a large family that wasn't mentioned.
I left the date and didn't sleep with her, and struggled to schedule another. I gave up. Then she got back with her ex.

For the better part of a year she kept sending mixed signals and would make sure I knew when they weren't together. Continued on and off BS.

We got to a point where we talked and texted again, she gave more hints about wanting sex, even getting all touchy while at work. But she was with the boyfriend still.

After more of the on and off and the conversation always being about the boyfriend, I just don't bother talking to her anymore.

But she's started trying to find any excuse to talk to me and gets very jealous when I talk to any of the attractive female coworkers. She'll even come interrupt just to stop it or try to talk to me.

My friends say two things. She's upset I didn't act on her advances or she's still super into me and wants what she can't have but won't leave the boyfriend due to comfort.
