Is there hope for a Baptist and Church of Christ relationship?

I’m Baptist and my boyfriend is Church of Christ. We’ve been dating for a while and I know we can both see each other in our future. We’re perfect for one other, we respect each other, and we understand one another. It’s the best feeling in the world. A couple months back he brought up the “m” word. I asked him how he planned to marry me if I’m not in his church because they feel like you should only marry within the church, only other members of the church of christ are going to heaven, etc. He said we could go to separate churches like we have been. The problem is that I don’t want my kids to be confused and grow up in a divided house. Our faiths view things so differently that one almost completely contradicts the other. I need help! I love him but I love God much more.
