Fiancé trouble

My fiancé and I have been going through a really rough patch. In the beginning he treated me so romantically and loving. The love never went away but we are both very career driven and our connection simmered down fast when I moved in. We have had our arguments and disagreements and unfortunately my family (mostly mom) knows most of the details - my fault for running my mouth. He has never physically abused me or called me out my name, he always makes sure i’m good whatever I ask he provides, he is my best friend but he can be a bit much at times (he is very stern x-military). We had a miscarriage recently which also caused a wedge. He has a son from a previous marriage that lives across country and wants to move closer to him. I was kind of hesitant to move because I don’t want to be away from my family either. I moved out recently after he admitted he was questioning us breaking up. Now he’s hard pressing me, He still wants to be together and is asking to go to counseling and says he still wants to marry me. I’m worried my family will never accept him or our relationship because of what we’ve been through, and if this can actually work. But I find it encouraging he is actually willing to try to fix our relationship and put in the work. I do love him very much and am willing to compromise and fix this but I don’t want to make the wrong choice. I am so torn 😞 any advice?
