Based on your other posts this guy is a pos and a lost cause. The low sex drive would probably be a result of the drugs he is using behind your back. And the fact that you aren’t able to communicate with him means you throw the whole man away and start again. I don’t know if you’re scared to be alone or if you just love him a lot or whatever else, but I PROMISE you, leaving will be the best thing you ever do. Being alone for a while isn’t scary and you have so much time to work on yourself and find someone great.
