I'm Going To Carry My Ex Husband's Baby

I feel like thi story is gonna get my judged even though I don't think it's a bad story. So me and my ex husband separated years ago. He ended up getting remarried to a man (he's pansexual) and I... well I went on dates but nothing good came out of it. I love my ex's husband. He's amazing with the kids, very respectful to me and everyone. Well I ended up getting pregnant by my boyfriend at the time and he cheated and left me. So I had to go threw my whole pregnancy alone. Then Covid hit and no baby shower. My ex and his husband decided to throw me a kind of quarantined baby shower and surprised me with a few gifts, a cake and everyone had on masks and gloves. We all stayed 6 ft apart. It was the sweetest thing anyone has ever done for me. After I had the baby I kinda got ppd. I didn't really have any help. My mom only came over to take cute pictures and leave. When my ex came to take the kids, he said if I needed a break, he would take the baby too, even though it's not his child. So he and his husband would take our kids together and my daughter. It gave me time to sleep and time to see my doctor. My ex's husband even referred me to HIS therapist who was honestly amazing. I was even struggling with formula because something was going on with my WIC so he bought me 5 large cans and refused to tell me how much it was so I could pay him back. Anyway so that's some back story on our relationship. A couple weeks ago, he and his husband said they wanted to talk to me. I told them they could. They go into how they've decided to have a baby. I was happy for them. I figured they were gonna adopt or get a surrogate. Well they asked ME to be the surrogate. I would lie if I said I wasn't a little surprised. They said there would be a donor egg my ex's sperm (his husband is infertile) and I would just have to carry the baby. They got the bun, they just need an oven. I told them to give me time to think about it. Well I made the decision to do it. I know a lot of people are gonna think it's weird, but I don't really think it is. I had actually thought about being a surrogate for someone since I'm done having kids, so I guess this is my chance!

Edit: Thank you for the person who told me about things that may disqualify me. I'm no longer on WIC. I started a new job and make too much, which I'm not complaining about. As for the ppd, I didn't know that. I'll have to definitely look into that, but thx for the support everyone!
