Should I go out with this young guy after what he did and how I feel about my ex?

So, I matched with a 24 year old back in January on Hinge and I thought we were hitting it off great but he ended up choosing another girl over me.

So we stopped talking and months later he ended up messaging me again and I messaged him back out of curiosity.

We've been talking sporadically for a few months now. And he lives an hour away but will be coming to where I live for a drill he has for the army and wants to go on a date.

I accepted but I'm not so sure if I should have.

For one, I'm not completely over my ex yet and for two, I still don't like how he handled things back in January. Making me think he was into me and stringing me along when he was into another girl at the time.

And now I'm not sure if he's doing this to try to get over her and I'm a rebound just like I'm not so sure I'm just doing this because I'm not completely over my ex.

But I know that I need to try to get over him and maybe going out with this guy will help.

I don't know. What should I do?
