OP, you’ve previously written about your dysfunctional relationship with this alcoholic who has a porn addiction. You sold your flat in August. Have you bought another place?
This guy was bad news before, and you said, “He was just not the man to build a solid, happy, healthy future with.” With this additional information regarding his hostility/detachment, you need to face, once and for all, that you will forever be dragged down and diminished by him.
After years of pouring yourself into your work, you wanted more of a balance, so bought your flat. You lived together there, but the relationship became unstable. Besides his addictions, you were at odds regarding having children, future housing, and general life goals. You felt the relationship had stalled and you wanted a family life and more room, so you impulsively sold your small flat but immediately regretted it, as you and he had no real plans.
You wrote in September that you’d broken up and you were dividing your time living as a lodger and with your alcoholic mother. As of last week you were still broken up. Have you actually resumed this toxic, dead-end relationship that fills you with anxiety?
You deserve happiness and stability. I would advise you to definitively end things and seek the support of individual counseling to strengthen your self-esteem.
