I fell for a guy twice my age

I fell for a guy twice my age. But I have stopped myself from having a proper relationship with them because of the age difference.

I am trying to move on but really have a strong connection towards them. I have stopped contact with them recently but I have been feeling down always and I want to contact them but I don't.

The only problem is I see them at a dance club weekly and it hurts my heart when I see them. They wanted to speak to me and know me but I don't think I can. I tried not to speak to them at the club but they wanted to talk to me and were laughing at me when I was ignoring them.

Every time I see them my heart always has a strong energy, I feel happiness and they have always treat me well. Though

when I am alone and reflect on the situation my heart hurts. I know when they find another partner it will hurt me. I enjoy going dancing and I don't know what to do about the situation. Any advice?
