I would like to help you with your question.
This woman seems to have many, many problems in living. Some of those issues are physical - allergies - and some are emotional - talking like a baby and being rageful. As you wrote, almost everything bothers her or is a problem.
This means that living with her would be constantly chaotic as she is rarely satisfied or happy.
What reasons are there for you to be in a relationship with her? What do you get out of this?
I don't think there is any way to break thru to her. Going to couple's therapy probably wouldn't be helpful as she is such a poor communicator and seems very selfish.
But why would you want to be with someone you felt such pity for?
What joy did she bring to your life?
What kind of partnership could you form with someone who yells and rants and treats you badly?
Was there any warmth and intimacy here?
I'm not trying to be negative...but rather trying to get you to see reality.
I'm very sorry this has happened. And you were a good man for trying so hard to please her. But there is a point where you must make decisions that are in YOUR best interest.
And...I'm just not sure that you are getting anything out of this relationship.
It's really sad that she couldn't accept your good intentions...but that might because she really has serious psychological problems.
Yes...I bet that's what you thought...that she would make a good companion and partner.
Likely only with therapy and maybe medication. She needs a full workup by a physician and also by a psychologist.
It's a tough situation. Sorry.
It probably is for the best. It will take her lots of effort to get well and stay well.
You are welcome!
I wish you good luck!
Is there any last thing I can help you with?
That might be a nice gesture on your part.
I'm not sure that she will listen...but you can sure encourage her to get help.
You are very welcome.
