Help me thru this sitch

[Pudmuddle]

I was just curious about something. I've noticed that my H has been kind of 'mimicking' my behaviors lately. I feel like I either have a parrot or a toddler hanging around me. LOL

He seems to be being sweet as pie showing respect to me, and making sure he does not say things 'accusingly' as he puts it, and also a couple of times I have been singing to myself (in hopes of boosting my spirits when around him) and now he is singing to himself...what the heck? Is this a good sign? Actually I find it kind of amusing as he doesn't really seem to have thoughts of his own lately...it seems he has been listening to someone(not me) and then repeats information. It also seems now he is doing the same thing with me...

Has anyone experienced this? Is it that his thoughts are so jumbled and confused that he doesn't know how to have his own thoughts right now? Oh and the more and more I read on midlife crisis I KNOW this is what he is experiencing and what I experienced 4 years ago...it all makes sense now.
