<human>: I have a friend who is dating an older man. He is very established in his line of work and is also public figure. He seems to be somewhat uncomfortable introducing her to his friends and having her introduce him to her friends. They've been dating for 6 months or so. He's always so "busy" all the time there's no time to do regular social activities with other people.

Is this normal behavior? I think it's strange and I'm a community person as well though I'm not in politics.

I'm getting a weird feeling about this situation for her and wanted to see if anyone has experience in this one.

Thanks!

Could you distill the essence of the text into 1-3 sentences?
