Is it weird to get ideas like this?

Ok so I still have my dog from my previous relationship with my ex girlfriend. He would light up whenever he was around both of us his tail would be going crazy. We have since moved into different apartments. Now I know by dog loves me but there was a couple who was at the dog park who brought their dog and he ran up to them wanting attention with the same look he would give myself and my ex girlfriend. Is this reason to possibly entertain rehoming him where’s he’s interacting with multiple people and not just one person all the time. Also I wanted to state that when I seen him go up to them it slightly brought a tear to my eye because it hurt my heart and I was thinking I’m sorry boy everything collapsed.
