The very next day he asked me to come over and hang out for the evening and we had a fun relaxing time.
I hope you seriously work with your therapist and psychiatrist on the reality of this situation vs your fantasy of happily ever after.
I’m not really understanding what was fun for you? His drinking? His lying? What about that night was so much fun that you gave away more of your dignity by running over there when he called? What was worth that to you?
Not trying to be mean just looking at the reality of it all.
Was it that when he called you felt wanted?
Was it you needing attention?
I mean you get "something" out of this toxic relationship so I guess I am what is your something?
