Hello there,
I’m a kink blogger/intimacy coach, so I hope my words can save you some pennies 
Personally I don’t think you’re in marriage councillor, territory yet, and if anything, I think suggesting it could even make your situation worse. Your wife is going to hear that as “we haven’t had sex, our marriage is failing” - that’s usually the point at which spouses say “all you care about is sex”. That’s not true, I’m sure - you actually want intimacy with her.
A year of no sex is, surprisingly, not exactly “crunch talks”. On the grand scheme of things - you still cuddle, kiss, talk - you’re actually doing pretty well. A marriage councillor is probably going to look at that and wonder what the big issue is here, because asides the lack of sex lately, you are doing pretty well!
Now, let’s talk.
You say she gives you “classic excuses” but I want you to reframe that; they may be excuses to you, but they are reasons to her. You didn’t mention anywhere in your post whether she works, if you have children, caring responsibilities? Trust me, stress destroys libido like a dart destroys a balloon.
Second, does it have to be sex, or could it be, say, a handjob? I say this because both my husband and I work hard in our respective jobs (and have a very demanding Jack Russell who we adore but good grief he keeps us busy!) and there was a time when we just… weren’t doing it. And it wasn’t deliberate; we were surviving sex-free because we were both too stressed and tired for sex. So take sex off the table! Enjoy cuddling, kissing, talking, touching. Take the pressure of expectation off and just… enjoy one another again. Enjoy one anofher together: how about giving one another a massage, or masturbating together instead? That can be just as - if not even hotter- than regular sex!
Good luck, and I hope this helps
