The first year I just went full media blackout. Seriously. I listened to books, podcasts and watched Netflix. I stayed away from all social media and TV. Given that our anniversary is two days after Valentine's Day, it was especially difficult. By year two I was able to focus on the progress we'd made and did a bit better, but it was still hard. Each year has been easier than the last.
If you can't ignore it (because of kids etc.) focus on celebrating completely different kinds of love - love for your kids, friends, parents etc. It helped me that even as I grew up my mom never treated it like a specifically "romantic" holiday but rather than one to celebrate love in all its forms - so I used that to focus away from romantic love until later.
