Is it weird if your boyfriend calls another girl half his age just to chat? And she does it back and sends messages to him saying ‘just calling to say hi, will try again later xx’

My 54 year old boyfriend of a year has NEVER texted xx before but now he does it to this girl. It’s all a bit weird.

She’s a very pretty girl and married, so I just think it’s weird that this is happening and why she is so interested in him. We all go out together on group dates and they’re always bantering and joking around. She even punches him playfully in the tummy and once put her hand on his leg (very quickly to say something).

Also, I felt uncomfortable that he went to her place while her husband out. They had lunch together but that’s it. I think most people would agree it’s a bit…off?

Anyway, that’s me getting that off my chest.
