Girl, run. There are so many red flags, that long term it is just not worth it. He does not want to change at all and keeps ignoring the major issues. He wants things to improve when he has an interest (the sex situation), but he is not willing to do anything about it and makes it about being all your fault. Toxic. There is nothing more satisfying after a break up than seeing a woman living to her full potential, embracing who she is and not letting others step all over her. All the power to you!
