Are we horrible people for doing this?

My fiance has a 3 year old daughter with his ex. Since his daughter was born while he was a minor, he couldn't pursue rights to her until he turned 18. Right after his 18th birthday he filed for shared parenting and a paternity test, everything. He's desperately wanted to see his little one and to be a father all her life, but his ex has denied him all contact. He drops off gifts at her birthday and Christmas. He writes letters, calls, emails, and tries everything he can to work things out with his ex so that she will let him see his daughter. She just won't even if he stops by the house! So she is pregnant again. We didn't know this for sure when he filed, but now we do. The court date is in 2 weeks and people are telling me that she is really stressed out about him getting rights to his daughter and that she's been in "false labor" several times because she's so afraid of "that sperm donor and his skank gf" getting rights. I don't understand why because my fiance has never been violent or done anything to deserve her hate. I might deserve her hate because we were friends briefly before I got with my fiance 3 years ago. However, it was clear at that point that she didn't want him. Believe me he waited for her! Is it horrible of us to put her through this while she's pregnant? I feel bad that she's so stressed, but really it isn't our fault she's pregnant again and she could have worked this out with him years ago but didn't. So I don't know. What do you think?
