This girl is a serial cheater. If you are looking for a serious, committed relationship, look elsewhere.
That being said, hanging around, texting all the time, and seeing her more than she sees Mr. Twice-A-Week will not work. She is obviously an independent woman, who does what she wants. Don't smother her. Be aloof and demanding. If you don't challenge her then she will move on to the next guy.

Amazing, a woman who actually knows what she is talking about! (That was a compliment btw, if not a little chauvenistic

)
To add to this, yeah, bro. You've really got it twisted there. You already sound wayyy too needy. What this will achieve is her having two guys overly into her(depending how much her boy is into her), and she will go for the next man who is interested, but is very detached(Sp?).
You need to ease up. You're wayyy too into her and, sheesh. You're gonna seem so fucking needy.
In regards to letting her know you're seeing other girls. Be careful with how you do that, you sound like a bit of a cowboy, you're going crazy with all these silly ideas that are just going to mess things up for you.
Telling girls that other girls are into you, or, you're seeing other girls, or you're good with girls. It never comes off right, even if it's entirely true. She has to see it for herself. And especially with all the time you planned on devoting to her, all that effort, just gonna sound like you're chatting breeze.
The whole 'I'll be seeing other girls' and wanting to let her know, will sound like a silly pathetic ultimatum or attempt to make her jealous. Either way, it's showing that you're trying to get a reaction from her, or care too much about what she thinks.
I apologise if this sounds very ranty, but your original post made me facepalm way too hard.
good luck with it, let us know how it goes.
And listen to Zephyrine, she's smart.
