Divorce talk...

So awhile ago my husband and I had the divorce talk. We’ve been back and forth trying to work things out but always want to when the other has given up. This last time we decided that we truly wanted to try and make things work for our little family. Well... long story short, every part of me is telling me to not go through with being married and I’m wondering how I should go about telling him... he is getting deployed and almost everyone I have talked to says to do it once he gets back from deployment, but I’m not that type of person to be able to do that. So I just need honest advice on how to have this conversation with someone who used to be the love of my life....
