18 years........when I finally realized how bad my marriage was even though I couldn't get a divorce.....I withdrew into my own part wing of my house & had nothing more to do with him.......then finally left 6 years ago & just now getting the divorce (which is taking me too long to actually finalize)......sex is just NOT something I really care about or need & I do not believe in sex outside of marriage....so that is NOT an option for me. I believe it's an expression of love between 2 people & not a one person thing either.......so that's just where I come from.
