27 weeks and my husband wants to leave

Heather
Our 5 year wedding anniversary is next month. He is leaving this weekend to stay with a friend but it may be permanent. There's a good chance he's cheating but of course he swears he isn't. My two nephews, 13 & 12, live with me and love him so much. They're going to be broken hearted. I don't even know what to do. How is this my life???
