Please hold this thought in yr mind: normal men wont act like this, wont treat you like this. You can have a happy life. Many people w addictions just don’t get over them, especially if they wont go to AA or whatever is appropriate for getting help. We had to draw the line with my alcoholic father and my mother did remarry. You are so used to the misery that it’s hard to break free. You feel like if YOU do the right thing, everything will be OK. That kind of thinking is a horrible trap.
Keep going to your therapist, do the separation and stick to it. Make a list of what you want in a guy and stick to it. Join some activities to meet men who like the things you do. That works better than random online dating and men treat you better when they are accountable to a group of friends who know what they are doing.
