As I posted in a previous thread, I'm going through a stressful but amicable divorce (if there is such a thing).
Due to some of the GPer's comments; some positive, some not, I considered who is responsible for the happiness of self or partner.
Very simply, IMHO, everyone is resonsible for their own happiness. We decide to be happy or not. This is not someone else's decision. If someone chooses to try and make us unhappy and we allow it, that's our problem. We can choose to take it on board or reject it.
So, there is no point blaming other people. if we are miserable. Bloody hard to do, sometimes, but ultimately our happiness is up to us, not someone else.
Just my opinion.
