Weird and uncomfortable situation

ive been dating this guy for a while and its been great other than his friends... His best friends wife has been getting jealous to the point it makes me uncomfortable and he is starting to hide the fact we are spending time together now.. we usually spend 1 or 2 days together and only for a few hours.

Every time we are together his best friends wife will blow up his phone to play video games with him and he says no and she will start asking if he is out with a prostitute (which he is a virgin so idk why she’d say that in the first place) and tell him he is spending too much time with me..

Idk what to do but I sent this message to him

I really really like him and don’t want to argue or anything and I don’t want to cause anything between his best friend and him or me....

Any advice? Anything to help me in this situation? Help him in this situation? I don’t expect him to stop being friends with them. I just hope they quit talking crap about me because honestly they don’t know me and I don’t know them..

I hope whatever he says when he talks to them it will help.. I just don’t know how to deal with this situation
