Feel I am going mad - again.
Am I just over sensitive or a snob as he suggests.
Coming back from a night out we get talking to a group of women - he picks up the banter and adding my age, how he might trade me in for a younger version, how lucky I am to have him,  stupid things by always joking at my expense. He then says after it I love her really. Do I imagine the looks of these people as if they can’t believe what he is saying or is it in my head and I need to lighten up.

This isn’t a one off and along with other things he does I don’t know if I am too sensitive

Maybe hes on his high horse. It could be hes really jealous and acts out for attention. You could be overreacting. But honestly at the end of the day. If your feelings are TRULY hurt by these things that happen. It needs to be discussed. you deserve to find a solution and so does he.
