've got a good friend who just told me she's kicked her DH out - and I couldn't be happier for her, because it's long overdue! For her, that's her aligning herself with her values. Sad from some people's perspectives, but just what her life needs, IYKWIM.
Oh I definitely get what you mean, I suppose I am more looking at it from the perspective of the people that are really struggling whether that be emotionally or financially and they don't appear to be "happy" with much.

Take my gf, this morning at coffee, she was nearly in tears telling me a) about her pr@#k of a DH who has left her and 4 kids and b) she is struggling to feed them cause she was a SAHM with no income and her DH has cut all access to monies. Thats when I get all sad and feel bad/guilty discussing how happy DH and I are and how I just bought a Kitchen Aid mixer which I love!

What i'm trying to say is that their lives aren't "worse" than yours...they may be struggling in certain areas but thats only so that they can gain strengths in those areas kwim? They're infact being given a gift.
I suppose I am having trouble seeing where "the gift" is for them atm, when everything just seems so bad.

And yes I am very lucky that we are so happy, and I count my blessings every day in relation to that.
