Need Help before I blow a fuse.

[20&lost]

My W is doing the OP grocery shopping and using our money. Multiple times a week she is disappearing for hours at a time. Last night she woke me up at 12:30 to ask if she could go to his house to let his dogs out and was gone for 2 hours. She said that he texted her that his dogs had not been out all day and that he wouldn't be home for another 3-4 hours. When she asked me I calmly said that was fine by me and just went back to sleep.
