"Well, we've had a few interactions and I think we have a few things in common so I thought we should just hang out a bit and dget to know each other a bit better"
Blech. You don't need to apologize for yourself! Just leave it implied that if you're exchanging contact info, it's with the goal of meeting again. At most, you could say something like, "I think you're a really interesting person/I'm impressed by about you, maybe we should hang out again" - if she's not into you, you're not going to change her mind by persuading her. Just deal with that, it's part of the game.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
