I'm not happy anymore.We've been married for 26 years and the bad outweighs the good by far.We have 5 children

whom are all grown with the exception of 1 16 year old.My daughter and her 2 kids live with us as well. I have wanted to go to couseling for a long time,he won't go.He works alot and NO he is not "messinng"around.We have alot of family issues that are not EVER going to be worked out.He drinks alot but he says he's not hurting anyone because he is not a violent person or anything so he thinks it's ok but it makes me sick because he comes in EVERYDAY with beer.He will make promises about lets do this or lets do that but then he forgets because he is drunk when he makes the promises.FORGET getting help with the drinking,not going to happen. At this point my only concern is my 16 yr old who is a jr. in h.s. What will this do to him if we split? I know it won't be easy but he is already having some problems with grades/school eventho he is very athletic. My spouse makes good money and I only work 30 hrs a week so my income is limited but I can't do this anymore,I am miserable.
