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

So, I've kind of stumbled into dating a guy I've known for a few months over the past week. I added him on facebook because I had a bit of a crush on him, and it's progressed from there. We've kissed, and had clothed sleepovers, but nothing more. However, it's very evident that he's more into me than I am into him. I've never been in this situation before, I always seem to be the one who loves more and gets trampled on.

It's become increasingly apparent to me every time I hang out with this guy that I have a steadily rising level of anxiety due to the fact that I'm not completely over my ex, who dumped me about 2 months ago, citing his depression as making him unable to be in a relationship. I took it very hard, we live in a small city where we run into each other all the time, and we got together about 2 weeks ago and ended up having sex. I know that if he wanted me back, I would go back in a heartbeat. I keep unfairly comparing this new guy to my ex. I feel like a scumbag.

What do I do? Do I try to explain things to the new guy and tap on the brakes? Should I talk to my ex and try to get a straightforward answer of "we're never getting back together" so I can move on with my life? This guy is actually really great and I could see myself dating him without complications in an alternate universe where I didn't just get dumped by a guy who I'm romanticizing as perfect.
<bot>: Dating a new guy but can't shake off feelings for my ex. Am I being an asshole and am not ready to date?
