A couple of observations:
I told him I didn't like it and he told me I could delete her which I did.
Next time, HE deletes her. By 'letting' you do it, he can now be angry that you delete his friends (silly, yes, and trivial, but he needs to be proactive and take responsibility himself...)
I told him I didn't like it and he told me I could delete her which I did. But it still made me upset about it like he didn't care that I had asked him to not be friends with females that I thought it was disrespectful to me and his answer was I just don't want him to have any friends...[snip]...Should I just let this drop and see what else he does? Or should I really sit him down again and explain that I don't think he should be friends with females again?
I suggest TWO things. First, yes, sit down with him and talk to him. Use a very specific formula when you do it:
This is the WTFS (When, Think, Feel, So) formula:
you have single female friends
2) I Think
that you don't respect me...
3) I Feel
betrayed and unloved
I respectfully request that you no longer have single females as friends.
(Use your own words - I just inserted mine to give you an idea...)
Second, have you taken the Love Buster's quiz
with him yet? If not - make a respectful request that he do it with you.
You've experienced the pain of an affair already - but unless you do some work on your marriage there is still danger of a repeat - and what is more - YOU are in a position to do so (regardless of your objections...)
There's a HUGE difference between someone returning to the marriage - and someone working on recovery in the marriage. On top of that, it isn't just enough to RECOVER what you had. There were problems in what you had that resulted in an affair. Building a better marriage is always a good idea...
