Hi, I do get the "traditional" approach but to me "traditional" can be so limiting/restrictive. So I'm going out on a limb here and saying why not text him "happy valentines, babe" or something like that? Afterall it can be a two way street to tell each other how you feel about them, so just take that opportunity to let him know........if you feel that way about him.
Then if he doesn't give you anything positive back.....talk to him about it, get an explanation, get something you can work with him on (if you want to work on it with him, of course!). Just give him a litttle time to reply though
As for everyone else showing off what they got, well that's great, really nice, be pleased for them, but know that there's a lot more to a meaningful/loving/solid relationship than just.......if you're right there was absolutely no chance of him affording anything.........and yours may be even stronger than theirs despite not getting anything.
I would have a gentle word with him about even picking some wild flowers for you would be nice next time around though
Best wishes
Alison
