I would try and get her to go to Al-anon Cyndy. That would help her let go a bit maybe. I have been in controlling relationships before and it's not nice and makes you feel like you're going nuts. I wasn't able to make a single new friend when I was with my ex and he was highly suspicious of any existing ones. But I let him control me a lot. Make sure you have friends outside of the relationship (this is just a healthy thing to do) and don't let fear of someone's reaction control the way you live x
