I agree, Pooh. It's like that old saying about insanity being if we keep doing the same thing over and over expecting different results. It does feel as if you are going crazy when things won't work the way we are certain they should work.
But, whyme, it's your peace of mind at stake here, your life. For me, in order to feel in control of my life I had to stop trying to control DS and DD lives. Once I accepted that I was being too pushy (this was the hard one...how could inviting my family to visit be pushy? How could wanting to visit my GC be pushy?, once I realized that it was me who could stop the craziness,of their rejection, then my life began to feel less insane. I was plagued by all those questions that have no answers. I finally had to just take two Advil and move ahead. I had to accept that my relationship with my AC was going to be different than I dreamed it would be; I had to accept that I might not see the GC more than once a year; I had to accept that my life was going to change.
Yes, there are hard days, like weekends like this one, when my GD is having a party for her 14th BD (just for girlfriends);it still hurts to think I am not a part of that family occasion. I have to be ok with that and move on. My family no longer defines my happiness as a person. They are adults now, and I have to treat them that way. Having said that, I will never let them disrespect me again. On the other hand, I know I have to give them space to live their own lives.
