I am also curious if this friend knows how to say "NO" when she really doesn't want to do something.

Ugh I lived with a H like that for 33 years. He would say he would do something & when it came right down to doing it....if he didn't want to he wouldn't after saying yes.

It is irritating.

After seeing this in your friend & all the things you have said yes to & done for her.....I would re-evaluate the things I say yes to & just not do as much with her any more.

My yes's never have expectations of the other person(s) attached to them....but I am blessed because my close friends give more than I could ever possibly give back so any time they ask I do say yes because I appreciate so much all they give of themselves to me. Maybe she takes for grsnted the things you do for her. Maybe she doesn't really appreciate what you do or maybe she just considerd that your doing things WITH her is just spending time together.

Anyway you look at it, it sounds like some re-evaluation time of the amount of time & activities YOU CHOOSE to do with her.....doesn't mean you give up the friendship just make it more functional for you & if you do end up in a situation like this always discuss ALL of the "if-then-elses" that could possibly be involved & don't leave them up to chance or assumption. Sometimes we learn a lot on how to better handle things ourselves from situations like this. I have had many situations that I have just written off as a learning experience for me.
