So were you aware that you were causing her to be unfaithful and adulterous, even though her husband was a drinker/druggie?
We had mutual friends who told me about what was going on in her life. She and I worked for the same company but in different departments. I’d worked with her on projects internally and spoke to her about what was going on in her life when he husband showed up at the office one day and made a scene.
She was legitimately afraid for her safety after one of her husband’s “friends” showed up demanding money from her. She moved in with me after I offered her a place to stay until things settled down. It turned into a long-term situation, as I had a spare bedroom, and after he passed, I told her she was welcome to stay as long as she needed to get her life back in order. Over time and many evenings talking into the night, our relationship blossomed, and we wound up vacationing together, commuting to work together, etc.
I don’t believe I caused her to be unfaithful. He was dead just a few months after she moved in.
