How Old is Too Old?

So remember the guy, Griffin, from my Lit Study class? And how much I liked him? Well we have a few problems.

1. I have no clue how old he is, but the more I talk to him and look at him; I'm thinking he is up somewhere around 28-30. Possibly. And that is too old, even for me. Which is really unfortunate because I really do like him because we are a lot alike. Although our similarities brings me to problem number 2.

2. He is a huge flirt. I can't really say anything bad about someone being a flirt because I love being a flirt. Whether I am in to a guy or not, I will flirt with him. However, I don't find this a particularly attractive trait in a guy. I should clarify, in my guy. I am a fiery personality and while it can be really good, it can also be really bad. I get extremely jealous when it comes to romantic relationships. I would not be able to handle him flirting with our entire class like he does. He is definitely charming, but he's not prince charming :(
