There is a fine line between fighting for your girl and being overbearing. Push too hard and she'll move on. Don't push hard enough, and she'll fault you for that too. Good luck trying to find where that line lies, as it's different for each girl. My advice is to keep open the lines of communication regarding your exclusivity - it's not something she will forget, but a friendly reminder never hurts. Just choose your moments wisely. Don't take her out to a nice dinner and ambush her with the "where is this going" question because she WILL get angry. Bring up your desire to be with her in a casual, comfortable setting. Maybe after you've both stayed in and watched a movie or a ball game. Let her know that you're willing to wait, but that eventually, you'll move on. Make her realize why you're the better choice. Keep the conversation simple and don't become heated if she says she needs more time.
