Don’t blame you at all for feeling confused by this man, he does not play the game with open cards.
You are on the right track calling his controlling behaviour out, however he is always going to keep on trying to get back control by turning on the charm, only to expect to have his way again after he has worn you down. He is already trying to wear you down about anal sex. He has zero respect for your wishes.
Don’t beat yourself up about wavering and agreeing to let him in to talk when he refuses to listen to you calling the relationship off. Just learn from it, that when you tell him what you want, he doesn’t necessarily respect your wishes at all, he only sees that as a challenge.
It doesn’t matter if you waver with breaking up- many people have difficulty ending relationships, let alone with a controling man like him.
You have the right to determine how you prefer sex, and when or if you want to see him.
If you need, time take all the time you need, tell a trusted friend and get support if you need to take back control of your social media, your body and your life.
Don’t feel bad or guilty if you have agreed to see him and change your mind and then find that you really do want to get out of this relationship.
You get to determine when and how you will close the door on him, at any point you wish.
Understandable that you feel sad about what you thought you had with him. it’s great you can reach out to others to get clearer perspective on what you actually have with him and the controling abusive person that he is.
This shit man will no doubt go on to try to control his ex and other woman, it is his pattern and he thinks he is quite justified to play his cards that way.
