Don’t feel bad about putting yourself first. Considering how self-absorbed friends have been lately, they clearly have no problem with it themselves.
It’s true expectations were inflated but what you’re left with isn’t so bad. Allow yourself time to readjust.
You’re not going to walk around on eggshells. Either people can be upfront about what they want or you will continue to ignore them.
You enter a period when your judgment will be questioned, but it’s not enough to just dig in your heels. You need to be sure in your beliefs.
The person challenging you may huff and puff, but he won’t be able to blow your house down. Hang tough and you’ll prevail.
You see possibility where someone else sees a dead-end. Why argue? Let this person bang his head against the wall and maybe it will knock some sense into him.
