Do I have a right to be upset?

I had a situation that I was pretty upset about. So. My ex-husband and I have a ten-year-old daughter together. He has a one-bedroom apartment, so when she is there (approx every other weekend), she sleeps on the couch. I think he should have a bedroom for her or give her his bed with clean sheets on it. The living room where the couch is is where the front door is. Yes, locked but still. So I find out…he goes to bed at 8 pm, closes his bedroom door off to her and leaves her up…So, he wouldn’t hear if someone tried to get in! He also has a hearing loss, I might add. And no idea what time she goes to sleep on this couch. Is it me, or is this all kinds of wrong?
