What should I tell him?

Ha

My boyfriend told me that his other girlfriend coming over to visit him after 2 years of border lock down. He did tell me he is sort of worried if he can’t have sex with her.

His mind is all matter about us.

What and how should I talk to him? Albeit that I am okay that she needs him too..I took pity of my boyfriend though.

P/S: His other gf doesn’t knows that we are back together.
