I say this with sincere kindness....I am just a terrible writer.
Example:
You asked for advise....we share our opinions. Has it changed your mind??
This girl hasn't asked, she is already living with him, probably under his "spell" already or she wouldn't be there. She has had to see some red flags already. Do you really think it would help her change her mind?
I think we woman/codies fall into this "I am special," "I can fix him," and "He would never treat me that way, I won't allow it" thinking." Of course, we are usually wrong,
He is 40(?) and she is 24?? Kind of sounds like that's already a red flag on both their parts and I am sure her parents are already concerned. If not, they should be but they still have to let her make her own decisions. like we all have.
Lastly, if her parents find out and take a stand against him....your info runs the risk of isolating her from her family. That's probably exactly what he wants. Just pray for her, pray for him and give it to God. JMO
