To the OP,
I totally agree with you. Your parents did not find themselves in some unfortunate circumstance and need help from family... They were expecting to put you and your family out for a lengthy period of time. No question about it. Anyone who is preaching about 'putting ones self out to help family' is not on the same track. Your parents weren't needing help in some unfortunate circumstance. They were wanting to impose on you, and for you to enable a bad decision.
Take a word of advice here. Don't even get started trying to defend yourself to those who are saying you were wrong. They are not you. They do not know your personal situation. If you start defending yourself here, you will definately be feeding the dragon.
I have this to say to you and to everyone else here. Any parent who would tell a child that they must cut of contact with the other parent has some serious issues and is dead wrong.
Any parent who would just up and cut themselves off from their daughter and their precious grandchildren because they are not 'catered too' and every single expectation met, has some serious issues and is dead wrong. And, this is exaclty what happened. The OP did not do anything to infringe on her mother. She simply found herself in a position where she felt she must say 'no'.
Any adult who is able to provide a place for themselves to stay and simply expects anyone else to provide for them, just for their own convenience, has some serious issues and is just plain wrong.
Okay, now that I have cleared this up.
Here is what is important.
I have said this on many threads.
It is NOT about 'right or wrong'!!!!
Do not even feel that you have to defend yourself as being 'right'.
Anyone who goes thru life looking at every personal situation as who was right, and how was I wronged, is on a long and stormy road.
LET IT GO and move forward.
Your mother made her decision.
You are getting a good dose of who your mother really is and how she can treat you and how she can affect you.
You will be making a very serious and grave error if you fall into the trap of falling all over yourself trying to appease a person like this and stay in their good graces. It is very apparant that your mother has very little good graces left at this point. It would be a futile effort, and you would just fall into the trap of her continually using guilt trips and threats of cutting you off to control you and your DH and your family.
If it becomes possible to forge some kind of amicable relationship, then great!!!!
But, I would think long and hard about ever returning to the kind of relationship that you have had in the past. (planning trips together, lack of personal boundaries, etc....)
My bet is that your mother would never find the kind of relationship described above as acceptable. For her, it is all about her, and it is all or nothing. So, be aware that the kind of amicable but with clear boundaries relationship that I am describing here may not happen.
Your mother has cut others out of her life. And, she has shown that she can and will do the same to you.
Your best bet is to let them know that you love them and would love to speak with them, and then move on from there.
