DotMH1901 I'm 'sposed to be taking a break, but I just wanted to say that isolating his wife from her family and friends and controlling who she can see is a very dangerous sign of a manipulative and controlling person.
You may think I am over-stressing this but I would rather risk looking silly in order to make sure your daughter is safe and is prepared to look after herself in case the situation is serious.
Your daughter may need to educate herself as to what other "red flags" to look out for in a relationship. She should say no to his not allowing her to see her friends and family. Most of all she cannot accept a life where he controls whom she can see. It is abnormal. But before long she will be making excuses for him and not looking after her own needs. I know this only too well. Being "allowed" by your husband/partner to see one friend but not others is simply not acceptable! It is abuse! She should be free to see anyone she wants, (well obviously within reason - someone always thinks of somebody you wouldn't consider it safe to see!) I would like her to be fully aware that not letting her see her family and friends is wrong, a serious matter. It is not right in a relationship that one person controls the other's ability to see their choice of friends. Does he belittle her or make her feel stupid about her choice of friends by any chance? Some men, while not actually refusing to let their wife see their friends, make it so embarrassing or horrible for them when they do see them, that they stop seeing them anyway.
If she responds "yes" to several of the following, I would strongly urge her to rethink her position in relationship to this man.
For example;
-Is she consistently made to feel guilty, whether she did anything wrong or not?
-Does he show passive aggressiveness such as saying something nice, or helpful, but it makes her feel horrendous?
-Does he say she is crazy? e.g.If she says she doesn't like something he does, does he say "You must be crazy." Does he even say, he's worried that she's crazy or a bit mad or whatever words he uses to doubt her mental capacity/memory/decision making etc.
-Does he often make her feel small and feel like her needs don’t matter?
-Does he twist her words?
-Does he lie?
-Is he distant or emotionally unavailable a lot of the time, so she feels as if she's being pushed away for weeks or even months at a time, but he's unwilling to explain why? Similarly, does he sometimes just not answer her, not talking, giving the silent treatment no matter how hard she tries to get him to respond?
-Does he “punish” her if she gets something wrong or makes a mistake, say by lording the wrongdoing over her, as a form of power?
I found the above examples from the internet although I was a Counsellor and I have lots of books.
On YouTube there are just too many videos about this kind of thing. I think it leads to lots of muddle in finding the right thing. Some people are making videos which are not helpful. But there are some that are good. I think this one by Stephanie Lyn is very good:

"What is Emotional Abuse? SIGNS you are in an emotionally abusive relationship"
I like a lot of her videos, such as "How to Handle a Manipulative Person" and "How to Distance Yourself from an Emotionally Abusive Person" and "How to set Boundaries with a toxic person" and "Let's talk about boundaries with people".
and I like Dana, I think this one might be appropriate:
"What are Normal Deal Breakers in a Relationship?"

Dana has made a lot of very good videos helping people cope with, mainly, a Narcissistic person, but certainly an emotionally abusive relationship. She is a Mental Health professional.
Please make sure to keep in touch with your daughter at all costs. He might start to brainwash her. She is with him so much, if he is willing to keep her from her family then he is quite likely to be beginning to just wear her down.
I do hope things work out well. Sending love to you and your daughter, L
