Should i stay or should i go ?

been married for more years than i care to remember two fab kids but i am so unhappy my husband is not a bad person i just cant stand him we have no interests in common we had our first holiday without the kids a couple of years ago and it was a wash out and we have no conversation unless its about the kids he is not interested in anything i would like to do i feel as if i have spent my whole life doing wot will make him happy and what not to do like go out with friends cause i just get too much grief also i am starting to resent that i have given up family and friends as we come from different parts of the country and i have made all the changes and he carries on as normal i am bone weary of trying all the time even though the discountent is all on my side wot worries me the most is i thought i could stick it out till the kids were at least 16 but now i cannot even focus on next week let alone another three years but i am very worried about my eldests reaction ( daddys boy )
