My husband is converting to Islam

Hello. So my husband has recently expressed he believes Islam is the truth. He says he hasn't fully committed however that's because all his life he was told Jesus is Lord.

I am so deep in the dumps about this it makes me sick to my stomach. I feel embarrassed and ashamed. When we got married, it was built off the foundation of The Holy Bible and now I feel as if that foundation is gone. I just feel as if I was tricked and he hasn't been completely transparent with me about alot of this.

I don't know what to do. I'm thinking about our future together and I just can't have kids with him if that is what he believes. I'm mourning our God fearing relationship we once had.

Please any advice is greatly appreciated or even uplifting words.

How do I go about this? Can this work? Am I being rational thinking about the future?

I'm really really sad about this.
