Wondering where my husband is. He left 12 hours ago to go stay at his grandmas for the night and talk to her about us but I haven't heard a word from him since he left. It's not what usually happens. He's only left twice our entire relationship but he always texted me so maybe this is a sign it's actually over this time. Maybe we can't work out our problems anymore.
