She resents my child. How am I supposed to act if they visit? Quiet? Worried about potential conflict...?

When I was young and stupid I slept with a married couple. I'm not really bi, I know that now, but they were friends and I was experimenting. I got pregnant by the husband and tried to maintain the friendship and keep the baby, but they wanted me to have an abortion even after the husband went to a counselor with me and initially said we could make it work as friends and still take care of the baby. Wife was angry and didnt want to share resources or family time with another child. Since it was my baby she was talking about and I didnt accept the abortion money, the friendship unraveled quickly and I was harshly told that the husband no longer wanted to deal with the issues related to my pregnancy and the birth of his next child. So I gave up calling them, and they gave up calling me. I finally sued for child support after 5 years, and now they will soon be able to visit. They are still angry, now because of the garnishment. But I need help!! he's responsible-is that so wrong
