Wedding confusion.

Grace

Okay I'm fiance is a Christian he doesn't follow to the exact what they preach.

We have sex out of wedlock and he has children with his ex out of wed lock.

I'm wondering. He purposed to,me a couple months ago and I've been focused on planning this wedding.

I don't know how to go about it. Should I have it in a church? Or what. I'm So confused.
