Mending Relationship

My girlfriend and I were involved with the borderline mass shooting. In a time we have been separated but trying to come back together. She has a four-year-old son that I love like my own. I have been growing in the Lord and getting therapeutic help. She was much more effective than I was and lost people closer and was shot at. I pray that our relationship to mend and her walls and come in and let me be there for her and we can come together as a family. Right now I watch her son on her days so she can check in and out with what she is able. I also pray that in this time I step up as the spiritual leader of the family and guided her and her son to Christ. This is very hard on all of us, I pray that God gives me the wisdom to know what to do
