I would also suggest praying that God can help you love him again. A year ago, I was in your shoes... I did not love my husband, had an emotional affair with someone via email, but had two kids and did not want to destroy them. I had to get rid of the emotional affair. But, even then, I did not love my husband. In fact, just before leaving our children with my parents before taking off on our 10 year anniversary trip, I sat at the table with my mom and told her how much I just did not want to spend a whole week with my husband.
God has worked a miracle in my heart. I love my husband more today than I probably ever have. The week alone helped tremendously. We went on a Christian cruise... forced to be with each other all the time, but also had wonderful growth lessons throughout the week. I highly recommend it! It wasn't designed particularly for marriages, but still helped us strengthen our walk with Christ which by default strengthens our walk with each other.
Keep praying and keep your eyes on God. He never promised it would be easy, but He is not going to sacrifice you. He can help you grow through this time and your marriage will be stronger than ever expected or anticipated. Keep going.
