Will you wish your Ex a happy V-day?

so i added this girl for like 1.5 years and she was my first love and i was her first love. we both meant a lot to each other and we learned a lot from each other. she still means the world to me as a person. not necessarily as a gf or anything. that feeling is gone. but the fact that i loved her and how much she was there for me and all that i still have a lot of respect for her as a person. so we had a really nasty breakup and she said she didn't ever wanna hear from me ever again. so i was wondering, since v-day is tomorrow, can i wish her a happy v-day just out of respect? we have broken up for almost a month now. so good idea or bad idea and why?
