Everyone is dismissing what you feel. But I get you. Some men just make you feel so beautiful and feel loved. Every woman needs this. Especially a 19 year old who is just stepping out into the world. He was a perfect gentle man but didn't complement you? Maybe he is insecure that you will realise that you are too good for him. He must also be aware of your age gap. Maybe he doesn't want to think too much of yourself?

Anyway, my best friends, boyfriend make me feel good about myself. That's important for me. If I feel insecure around a particular person I just cut off because I don't like that energy. Nothing wrong with it. Don't listen to other comments here. Listen to your instinct. If you feel Something is off means it is.
