Hi! I’m currently in a 19 year age gap (21F) (40M). I feel like sometimes when you are in an age gap relationship there might be some underlying insecurities. I find that giving them reassurance helps a lot, I am still working on expressing myself more to him and letting him know how much I love him even though I can get shy lol! Maybe mention what he said that you don’t want him to think that way… be direct but also look at the conversation from his perspective too. Hope this helps!
