Dont let her changes get you down. You have no idea what they could be about. I know all about the checking emails and FB...I still have to check email sometimes to see if she expects me to be writing her. It is not good for us, but I sometimes just have to know.
Maybe you should read up on MLCs and see if some of that fits your W. It could explain some of what she has going on right now.(shoes, lipstick)
Also I see some great opportunities for 180s for you based on what you said. You procrastinate, stop doing that. It will make you feel better to not be that way anyway. Make that part of your goals and tell yourself that you WILL get those things done TODAY. And if you are normally dark around her as you say, then maybe try being cheerful. Obviously not to the extent that it is fake. I wouldnt put too much thought into trying to mindread here about the independent life. She may just want to change some things about herself. You never know. So dont beat yourself up about it wondering. You got this buddy. Maybe reach out to Sandi2 or MrBond, they can advise you better than I can.
