Glad I've just found this thread whilst pottering through this section.
Just today I sent dh a longish text telling him i absolutely love the bones of him but I'm really resenting him now
He is definitely a high functioning alcoholic.
For the first 10 years together he barely drank but has an addictive personality so knew not to.
The last 7 years have got progressively worse. He would go months drinking daily and then decide enough was enough after me nagging and would stop completely.
It would be a good 12 months and then something like xmas or a holiday would start it all off again and the cycle continues.
The same excuses and reasoning and sometimes agreeing with me that he drinks far too much just to get me off his back.
Well I'm close to the edge of reason now. He has an impulsive personality so over the years he'll get obsessed with collecting something and it's all guns blazing and loads of whatever it may be plus the cost then Hel suddenly say enough and get rid of it all 
I've told him over the years many times it's so draining. Why can't he be content with what he has.
He always seems to be chasing something better bigger or different.
In the text I acknowledged my nagging and comments must piss him off because they poss me off aswel however I'm now totally resenting him for not showing me I'm more important. I support him in every way inc practical and told him he does nothing for me right now and brings nothing to our marriage at all.
I said I don't feel like I want to be affectionate let alone intimate with him and that makes me sad because we've always had a great relationship and share a lot of laughs but not anymore.
I've said I can't continue like it is as it's bringing me down and making me feel not worth the effort or respect as a person or his wife and mother of his children and I have really disengaged the last few months to protect my own feelings but I wanted him to hear it from me because he's picking up on my vibe.
It's up to him now to continue how he chooses and not change anything or change things but I'm not prepared to carry on like it as I'm entitled to be happy and feel good not second fiddle to his needs.
We are both adults. There will be no arguing as I've gone past that stage and told him that's the worrying part in that I don't feel I want to waste anymore energy being angry or resentful I just want to enjoy good things in life.
He now knows how I feel. I can't and refuse to spell it out anymore.
But if things don't change I will continue to do things without him and I will leave him. Sad after many good years but that doesn't trump the crap times when they are now.
He hasn't had an alcohol free day since mid March this stint and each week the amount is going up. He knows it's a problem but only he can sort it out
