My significant other died six months ago from a long-term illness. In our 25 years together, we had a 25-year-old daughter and a 21-year-old son. During that time, he had an illegitimate son who is also 21 years old, just a few months older than our son. I didn’t even meet this son until he was 15. After my significant other’s death, he began living with me and my son. About a month ago, I developed a sexual relationship with my significant other’s son. My children have now disowned me, calling the relationship disgusting, a poor decision, and inappropriate. The way I see it, other than the age gap of 25 years, we are both single, both adults, we are not related, I didn’t raise him, I didn’t even meet him until he was 15 years old, and I was never actually married to his dad, therefore I was never his actual stepmom. Do you think my children are correct in their perception of this relationship, and if so, for what reasons?
