Dating advice

I'm 26 and started trying to date again a year ago after my only serious relationship of 6 years and I called it quits. Honestly I wish we had broken up sooner because he was emotionally abusive among other things. I've been on a few dates but nothing seems to go anywhere. I started seeing this guy recently and at first I was intetested in seeing where it would go, but now I'm not sure. He's a nice guy and so far has been a gentleman. He's into me but I'm not sure i'm as into him as he is into me. I can't tell if I'm trying to talk myself into being with him or out. Should I wait? How can you tell if its something worth getting into? I'm looking for a long term partner so I'm being selective (maybe too much?) I feel like I don't know what I'm doing and just when I think I know what I want, it changes. Does this mean I'm not ready to date?
