I have a mental issue and my husband is giving up on me?

I have had a mental issue about my husband seeing other women. He had a lusting issue years ago, but for the past three years he has not looked at or seen other women for me. He looks down when out in public, like the Muslim people do, he has not watched movies with the exception of Pixar movies, he turns off plug ins and pictures on the computer, etc. Recently he has been telling me that he can't do this anymore. He has always had a temper and he has gotten a temper about it many times, he has become more and more resentful of me. He told me today that he will not do this anymore and he put the pictures and plug ins on the computer and everything. I feel I am in shock because he has been not seeing women for three years for me and he is stopping now. I feel he doesn't care about me, I would do anything for him to not see women still but if he continues to not see them, I know how unhappy he will be and I don't want that. But I know now that he is seeing them again, this is going to destroy my heart and hurt more and more. I don't know what to do - Please I need help from somebody. Please don't write nasty comments to me because I DO know how rare and strange it is for me to have the mental issue I have. Please any helpful and kind advice would be so much appreciated.
