Did your husband during your marriage just deny sex and any sexual affection decrease prior to your mother-in-law hijtingb then everything sexual ceased to exist? Do you think that he tried to hide it because of his mother? And then once she passed, he was able to leave your marriage for this priest? I ask because my husband and I are going through such a thing except there's no priest and he denies being gay. Although he NEVER is sexual nor kisses with an open mouth and we haven't had sex in forever. I've stopped suggesting anything sexual because being given excuses and the anger like it's some chore hurts too much. Prayers for you and your recovery through this crappy situation. One more thing, God's word NEVER CHANGES.
