When you think too much, you start "getting in trouble." Why does it matter so much what his motives are? Can he force you to do what he wants all the time? Just enjoy a hug or kiss or whatever and go with it.
RE: messy house... my W and I had a conversation yesterday that went something like this:
W: this bed cover is toast M: yes, well I try to wipe up the spills as soon as they happen, but it doesn't help too much W: maybe we could get a nice new one sometime soon M: I guess so, but we should wait a few years until the kids are older W: this used to be such a nice cover... and how it's all sh*tted up - what happened to keeping things clean and nice and neat?!? M: we had kids
So, I think any household with young kids is doomed to live in a state of disarray and "uncleanliness" unless there is constant cleaning going on. Don't stress about it! Are your kids being ignored or going without things that they need?? I doubt it. You're doing your best!
