If the two of you are living together, then you may be continuing to think of him as your boyfriend simply because it seems complicated to either leave or ask him to leave.

You are unhappy being with this man, and that is not going to change. He is not going to change. I can't promise you that there is a wonderful man out there who you will find and have a happy life with. But there might be. Staying with this miserable butthole gives you no hope of a good future. Being alone, IMHO, would be better. At least you would be available to someone nice and loving.

If you settle for crap, that's exactly what you'll get. Don't settle. Write it off as a learning experience and move on. You'll cry for awhile (for a lost dream) and then you'll thank yourself.

You fell for this guy because you lacked experience in judging men - yes judging. You do have to be judgmental in deciding who to partner with. Maybe you thought you shouldn't judge, but just be understanding and open to love. Well, you see where that got you. Time for a radically different approach to life and love.
