DEAR ABBY: I made a big mistake three years ago. When I found out my husband was cheating on me, I became vengeful and sought revenge. I ended up sleeping with my sister-in-law's boyfriend to get back at my husband and at her for some things she did in the past. It took my pain away -- for a bit.
Abby, I am not this kind of person. I'm not an evil, conniving tramp. I regret what I did every day, and I feel like garbage.
My sister-in-law and I haven't spoken since I decided to tell her the truth. My husband and I (miraculously) were able to work through our problems, and our relationship is stronger than ever. My sister-in-law and her boyfriend have remained together, and I don't speak to him anymore either.
What can I do to earn forgiveness? Is this even forgivable? How can I mend this family I helped tear apart? -- ONLY HUMAN IN HOUSTON
DEAR ONLY HUMAN: You might start by apologizing to your sister-in-law for the pain you caused her. But after that, the decision about whether she can forgive you or wants anything more to do with you will be up to her.
