25 years of marriage, and not all of them happy :(

I have a question to ask.

My 25th wedding anniversary is fast approaching. My relationship with my wife has been crap for the past 2-3 years. I have initiated marriage counseling, but my wife refuses to go. She thinks it's nobody elses business but ours. My wife is VERY controlling. I'm willing to make changes and she isn't. She thinks I'm the one with the problem, not her.

Am I in the right for refusing to plan a party for the occation, or am I just being an ass?
