Hi Lupita,
I've made some of my best women friends as a result of doing meaningful group things with them. Women's support group, church covenant group, volunteer things. Somehow purely social ("let's do something...go somewhere...") don't seem to be as mutual.
YES there are good friends out there. It's good to practice saying Yes, No, That Works for Me, That Doesn't, I Can Do This But Not That, etc (without emotion--that's the trick...saying no, or setting limits, needs to have no shame or resentment etc attached).
One good shrink once said to me, In a healthy system, you're always free to comment.
I think social transactions can feel so loaded to children of Ns that we don't know that Yeses and Nos and Maybes (boundaries) can simply be information or comment, not a challenge to our equilibrium.
Hops
