No, I don't think he would ever abuse them. I think they are safe.
When they are with me, they often ASK if they can sleep with me because they "do at daddy's house" -- but I tell them, when you get up in the morning, you can come into my room and snuggle me -- so I get morning snuggles instead. Plus...my bed is queen size, not king like the ex's.

I haven't thought about asking him to cut back. BUT I DO want to go have lunch with them once a week when they are with their dad.

Yes, I do think he's lonely. I know how lonely is...and it's hard.

Anyway...thanks for your input.
