So a bit of a background, I met this guy in a dating app. I'm 37F and he is 52M, there is a bit of an age difference but he seem to have always dated younger women. We have been so far on 5 dates. Sometimes I notice, he openly checks women out when he is with me. I'm quite attractive myself and he says that to be very often. On one of the dates, we were at a club and he noticed a young girl (must be 20 not more) with mobile in her pocket with flash light on. He wanted to go and tell her about it because he said it could run her battery down and she could not get a uber back or something. The girl was almost half dressed, quite attractive and clearly a bit drunk but she wasnt alone, she had 5 friends with her. He could have left it to me to tell her or her friends to tell her, but he went really close to her and whispered something in her ears, then the girl puts her arm around him, then he points at me and says something. He got back to me and said, "you know she must be attracted to be coz he started putting her arms around me" . The whole thing I felt was unnecessary if he had left me convey it to her.
On the second date he was telling me about an incident that he found a girl in her 20s looking at him, this is something he should have avoided mentioning it to a date. He is also nice to me so far other than these red flags.
Is this my interpretations and jealously or is he playing up or is he really attracted to much younger girls and I should run away from this guy?
I genuinely want an honest advice on this please.
