Marriage in need

I ask for prayers for my husband and I. We've been together for four years and he has recently told me that he doesn't know if he can go on. He has been traveling a lot due to work and now spends more time away than at home. We have two children and I fear that he's staying away to avoid me but it only hurts us and the kids. I ask for God's help that we can make our way back to each other. I ask for anyone who can pray for us that God touches our hearts to heal us and our union. Thank you and God bless.
