Without reading anything more than the first post it sounds your predictability and doting is boring her. Some women take comfort from it, some become tired of it. There is not one rule works for all in any relationship as people are all very different but I suspect she has power over you and has lost a little respect.
Many ways that can be fixed, but it might be best to start with rekindling some old friendships and having a few lads nights. Nothing raucous and don't cause an issue with her nights out at this point, but start doing stuff on the spure of the moment and if she moans do what she did to you.
"Tough, see you later".
It will either shake her up (which may take time and pain) or blow your world apart but if that blows it apart it's past broken I'd suggest and might be time to move on.
