Don't charge people for likes, roses, etc. If you want people to stop using your app that's a great way to get folks to do it. Everyone knows online dating is a numbers game for both genders. Purposefully hamstringing your users with a paywall after a certain level of use is lunacy. The $30/mo price tag for premium is hilarious. You have no premium features to speak of, and you don't have proprietary tech over Tinder or Bumble why on earth would anyone pay for a worse version of those apps?
