No relationship is perfect. A long-term relationship requires constant effort to understand each other, fix misunderstandings, solve problems and continue to grow as both individuals change and evolve. How we deal with our misunderstandings is the focus of this community. Join us to find support, get advice, and share your experience with your relationship.

I think it's very good that you are making plans and getting educated.
I have been divorced from her for 6 years now and I still have personal issues from the abuse not to mention suffer from PTSD. You need to get out of that situation ASAP as it can take a long time to recover.
Big hugs and I wish you luck!
If you think he may be physically dangerous take steps to ensure your safety.
I ended up leaving in a terrible financial state however I felt so much better almost from the day that he was out of my life.... Life improved tenfold and once he was gone he was gone for good... He'll want to get in touch again and love you.... I let him know in no uncertain terms it was done
I learned a lot of good lessens getting out of that marriage.... Big hug for you.... I wish you well....xo
Hugs to all of you going through this as well.
I can't afford these things right now, so I've gone through my employee crisis program which allows me some limited counseling that has been a tremendous help. I've also looked up support groups through meetup.com
The best thing you can do for her yourself is just be there for her to talk to. Understand that confusion will come with the emotions that are going to overcome her. I constantly doubt myself and sometimes feel like all the issues and problems were my fault. A narcissist is very good at making their victims doubt their own judgement. Keep telling her that she's on the right track in removing herself from a relationship that brings her so much pain. I have listened to a few audiobooks on abusive men to help me get a handle on what I'm dealing with and help with the self doubt. I'll put two of the most enlightening book titles at the end of this. These books will educate you and your Mom on the manipulation and thought process of an abusive man. I hope your Mom gets through this time quickly and starts believing in herself and her own strength. Good luck to both of you.
