The guy I'm seeing is on Tinder, should I be concern?

I have been seeing a guy for nearly three weeks and we are in a relationship. We met on Tinder. He introduces me to his friends and parents as his girlfriend. We went alot together. Cut story short. We decided to delete tinder and he was the one that delete it right in front of me first. We were together and someone randomly sent him a message on tinder. So I was like "I thought you deleted it". He said "It was for banter and okay to be honest I still keep in contact with someone if my uni hometown and I will ask her contact and delete tinder." I said okay to that and today I asked him "Have you delete tinder" and he said he have but I could see his last seen... I just dont know if I am over thinking. I do not want to be pushy..should I just let it go and forget about it?

Do you know his Tinder username? Create a fake account of someone who looks hot & see if he answers it's messages.

I've done that and he didn't swipe backk...
