AITA for not wanting to sign away my rights?

Look I know it’s my choice and I have a right to say no but right now it feels like the rest of the world doesn’t agreeHonestly, I (26m) didn’t know this woman that well when we first met through a dating site. She was 35 and according to her profile was single, never told me she was married. We went out on a few dates for 4 months until she told me she wasn’t interested anymore.I later found out it was because her HUSBAND was getting suspicious and she needed to cut her losses. But a few months after she contacted me again and told me she was pregnant.It hadn’t been that long since we slept together and she confessed everything. Her husband still didn’t know yet because she wanted to find out who the father was first.We did the prenatal paternity test and confirmed her baby is also mine. She had to tell him after that and it was a shit show. He wanted to speak to me and called me like crazy. She got him to leave me alone after telling him I never knew about her being married. We were both lied to by her.They’re apparently trying to work things out but here’s the thing. Her husband wants me completely out of the picture and is willing to adopt my baby if I terminate my parental rights. He doesn’t want me in their lives at all and this is his only condition or he’s divorcing her and taking their 2 kids.Don’t know if he can actually do that but she’s begging me to do this or it’ll completely break their family. Neither of them are considering that this is my child too and I want to be in my child’s life. I said I would not and it’s causing all these problems.She’s called several times telling me how badly this is hurting her family and her kids are hurt and confused because her husband’s temporarily moved out until this condition is met. She feels guilty for doing this to them but says she wants to fix her mistakes and make their marriage work if I could just do this.Plus to her, it’s a sweet deal for me since I won’t ever have to raise this baby or be responsible financially. I don’t see it that way, I wanna be a dad to my son. But it feels like what I want is hurting everyone else, like her kids.My close friends who know all this get I wanna do right by my kid, but feel I should walk away from this messy situation as it’ll always be a part of my life if I choose to be involved and it’s possible if her husband is willing to adopt my son after birth, he’ll have a good life.Nobody else in my life thinks me being in my son’s life is a good idea and I don’t know if it really is such a bad thing.She’s due in 2 mos and I don’t know what to do.
