Hello and welcome Jude Frances!

Those are some pretty big questions but you've come to the right place. We can help you find the answers and work on ways to make your relationship better.
Trying to reason, getting triggered by blame and projection, disengaging, setting boundaries -- those are all very familiar themes around here and things I've been working on myself.
Just to get started, here are a couple of workshops that might be helpful for you:

Details help us get a feel for the dynamic and will help us see what tools might be most helpful to you.
Again, welcome! Keep posting!
