First off, this guy is a jerk and you are better off without him. Hollow, yes, especially with all you are feeling.
I am really serious n this though. Think how self centered he is to ask this. How he can't possibly be even considering your feelings. You don't need that. So yes, you dodged a bullet.
Get a cat. They love you forever and unconditionally. I recommend a Russian Blue. I have 2, and they are very affectionate. Love laps. Mine greets me at the door when I get home and hops on the table to say goodbye when I leave.
That said, I got him when I had been through two back to back really bad long term relationships and had given up on men. He really helped emotionally as it was nice to have a not empty apartment and someone who was waiting for me.
I eventually tried a dating club like you did, and it worked out horribly for me. Back then, there was no dating websites, so I figured I was destined to be alone with my cat and focus on my career.
I did meet DH, but it was later, and by accident. I have no good advice to give there.
