Guys help!

I’ve been talking to ( having sex) with this guy for a few months now. We have had our ups and downs but still remained pretty good friends. Anyways as of lately he has not been calling me. I’m assuming because v-day is around the corner and he doesn’t want to buy me anything smh I honestly could care less but the sex is awesome and I would like to keep him around s big longer. My question to you guys is should I reach out to him? Btw the guy is super rich however I have never asked him for anything
