Husband left me with 5 week old baby.

My husband left me about 5 weeks ago when our son was only 5 weeks old. He left because of issues with his daughter and family that we had and also he says I am always negative and complain about things like our wedding. We have only been married about 7 months. He is still supporting us financially but I want my husband to come home and our marriage to be strong. Please pray for our marriage to make it through this difficult time! Thank you!
