In short buddy,

Like thousands of other guys who are already posted topics expressing this exact same emotion you've began to obsess over her. When you obsess over a girl you begin planning for her to be in your life, and when you do this and they don't react in the way you had it pictured in your mind you become compulsive and to CONTROL them so that you will not be met with this disappointment again. You don't actually like the girl, because if you did you would be open to letting her be. You want to POSSESS her. And love is not possession. We can only possess things without free will.

Men have to learn to take your dealings with women one day at a time. A woman will naturally prompt you for plans of a future with her. SO when you begin to do it, in too much of a hurry emotionally, you are replacing the position that she enjoys to play in the relationship. You're becoming emotional and expecting her to BE THERE for your emotional needs. But that is what SHE WANTS, men have to figure out how they have become the ones in which desire that which women once desired from them.
Its oneitis. Mild oneitis, but one the road to becoming full blown oneitis unless you can get your mind in order. Scarp all the future plans and scrap the gift for now. Pull back, let her come to you a bit so that you can restore balance in the relationship. Pull for as long as it takes. Giving into to the desire to weakly reach out more than you should will further disrupt the balance you're seeking to restore the path to a successful relationship.
