heartworms.net



I don't really know where you found the $11 cpc info.. Google keyword tool shows a CPC of $2,88 and around 1,600 exact monthly searches..

If you do not develop this into a money making website then you will not get much for the domain itself.. Not enough searches or cpc to have any large value..
 
To 'worm your way into someone's heart' isn't a particularly endearing expression. It means you had to slowly, actively manipulate someone over time in order for them to eventually like you. Not really very good for a dating site's image.

'Heartworms' is worse; it just sounds like a parasite:
