🆘Husband refusing to help pay for IVF 🆘

Hi ladies. I need some input and I can't ask people in my personal life.

So, my husband and I found out that due to medical reasons we will need to do <a href="https://glowing.com/glow-fertility-program">IVF</a> to have baby. We've seen an RE and they found that the problem is on my side.

They told us it would be about 20 grand or so. I'm ready to start saving money, but he doesn't see why he should help save up for it.

I don't know what to do. I realize the medical problem is on my side, but the fact he's refusing to pay for any of this is so hard. We've been married for 4 years and together for 6. I've never seen him act like this before. Could it be that the price tag is too much, and he's worried about that?

I realize we're in this 'through sickness and in heath', but is in unreasonable to ask him to help pay for this?

What if down the road we have a child, and they get sick? Will he refuse to pay for medical care for our future child?

I don't know what to do...any input would be appreciated 😓 😖
