I hear a comfortable, confident blue is good for a dating site. But I leave that mostly to you.

I need a logo for a dating website for Catholics. It should feel young, hip, and clean. I like minimalist designs like airbnb, digitalocean, apple, and this 99designs site. If incorporating any symbolism, I prefer dating/chemistry symbols rather than religious symbols.
I want to make note of a feature that perhaps could be incorporated into the logo somehow: on every profile in the site there will be an icon indicating whether or not the current user and that person have expressed interest in (or "liked") each other. See the beaker in the left-hand column in the 3rd and 4th screenshots to get an idea of what I'm talking about. The icon might not ultimately be a beaker, but it will be some icon indicating mutual interest has been expressed. Should that be incorporated into the logo? I don't know. Just throwing that out there.
I've attached photos of a temporary webpage design I came up with to give you some idea of where I'm going. These photos DO NOT represent the actual webpage design which may ultimately be completely different. I will run a subsequent contest for a webpage design to go with the winning logo from this contest.
