Why not try redirecting it to a dating offer for now instead of parking it? If the traffic is good, you should make more that way.
Dating is hugely competitive, and even with a good domain name you're going to have an uphill battle to climb, especially in SEO. If you're going to develop it into a brand, then be prepared to spend lots of money doing that.
It's not close to being a millionaire name unless developed and popular, but then again, that can be said about almost any domain name.
Park/redirect and sell, or hold onto it if you don't need the money. Value will go up and you'll get more if an end user approaches you for the name rather than you putting it out there for sale -- you'll mainly just get other domain investors who won't pay the top dollar an end user would.
