My sons girlfriend has been having sex with his friend ??

Why the hell would you want to insert yourself in the middle of this drama?

My sister is friends with her mother. She finally told me about it

ok way too many people are talking about none of their business

if your sister/mother are talking about this, just imagine what they're spreading about you

do not encourage them to gossip - shut them down when they start

__

this is between your son and his girlfriend - not about her mother, your sister or you

shut down the gossip - and tell them to stop spreading gossip

I think you can have a conversation with your son about his relationship without bringing in the gossip.

You can ask how things are going. If their relationship is exclusive. How serious are they. What he like about her.

Just to get him thinking.

I have 2 sons (47 and 28) and one grandson. (22) I would begin a conversation just to see how serious they were. Maybe they are just dating casually. Or maybe he’s not that serious.
