I can’t believe the majority of responses on this thread. Such, judgement, anger, bitterness being thrown at the OP. And yes I have RTFT. I lost count of how many pp called the OP selfish, then there was the possibility of developing PTSD and a personality disorder! Just shows what happens to women who step out of the lines of social conformity. Such a total lack of understanding and empathy, that we are all different and have different needs. And no, I don’t think you have to place this all on hold until they go to uni.
So many posters saying “but why not take them?” Isn’t the point to get away and be an individual for a while? So many accusations of being selfish. The origins of the word selfish, mean “caring for the self”. I have been a therapist for 20 years and support my clients in developing their ability to care for themselves.
A child with a secure attachment to their parent is unlikely to be psychologically damaged by this break, if it is well managed and there is regular contact whilst away. As a caveat, no one can be entirely sure how a family will respond to a separation, so there is an element of risk. Most likely to the marriage, if one or other of the partners decides they prefer solo life. But if the OP really wants/needs this, there are risks to the marriage of not doing it. Consensus is important.
It has been interesting to see the lines drawn around what is acceptable (according to some PP), for a mother to do, such as, it’s ok to go for a spa weekend, maybe a week in Spain, weekend breaks with children, but not spouse. But don’t dare step out of the lines of social conformity, or the vipers will attack.
Parenting is all consuming these days. I work full time and spend my weekends running my 12 year around social activities, as do all the parents I know. It wasn’t like this for my mother in the the seventies and eighties. I occupied myself, as did all my friends. So no my mother didn’t “fuck off for 9 weeks”, but parenting was nothing like it is now.
More parents should take a break but particularly mothers who often hold the responsibility of wife work for decades sometimes.
I know OP has said, she isn’t going and was patronisingly told “well done”.
OP, I hope you reconsider and care for the self!
