Wrong to be with a younger man

Hi,

My long relationship with a guy who I supposed to marry finished days before the last Christmas. I was so devastated and did something crazy. I left my number to a guy who was my server at a restaurant. He contacted me the next day. We texted until I told him that I will be leaving in a couple days to the other side of the world. That’s where I live

We ended up having sex the last two nights. However, he is 22 and I am 34. I tried to tell him that I was not looking for a relationship because he needs to live his life but he insists on keeping in touch.

I am confused as I am still recovering from my break up but would like to give this guy a chance. However, it feels wrong for the age gap.

Any advice would be appreciated
