he's chosen to self isolate with his wife and family, he's made he clearly would rather be with her and have "brief" shags with you. This has already proved you're just a person that's only worth limited time
I think using the word “chosen” is a bit optimistic here.
Most people having an affair would choose to self isolate with their affair partner. Not their spouse, Let’s face it. Given a straight choice with no complexity involved.
Self isolating with their spouse is going to be more about logistics, complexity, kids, finances and many other things, but it’s very unlikely going to be simply about a simple preference.
If they preferred the wife or husband they wouldn’t be having an affair in the first place. No way round that unpalatable fact. I think you can almost always guarantee that when it comes to affairs, they prefer their affair partner to their spouse at that point in time.
