DEAR ABBY: I have been married to a wonderful man for six years, and we’ve been together for 10. We bought a house a few years ago, and since then our sex life has significantly decreased. I know the stress of being homeowners hasn’t helped our situation, and over the last year I have felt like I’m falling out of love.

A few weeks ago, I ran into a man I dated before my husband, and there was a spark between us that neither of us can deny. He broke my heart years ago, but I can’t shake this feeling of wanting — needing — to be with him. I can’t get him off my mind.
