After many years of not mentioning this, my husband just revealed that he masturbated because I gained weight. There was a time when he didn’t have sex with me. I often told him how much I missed being with him. I never knew he was self-pleasuring as he drank so much and I considered it the reason for no sex. Even after all these years, I am very hurt. He is older than I am, and can no longer have sex. How can I resolve this?
