I know it's been a few days since this post, but I would like to add something (if it hasn't already been said).
Your wife sounds like me on a bad day - when PMS and hormones are involved. You did the right thing IMO in supporting her and being quite kind and generous. It's tough having hormones I can tell you that! Even if she pushed you away a bit, don't take it personally. She will remember that you made an effort.
It's really tough when hormones are raging - there is little control it seems. Mind you, for my personal situation - I have done so much to get myself under control but it's still hard work.
I don't know if this was the case during that time - I hope it was!
If not, then yes, she has been doing a lot of thinking - which is a good thing in itself.
