Search Results: hooking up with best friend

So i met this girl this past new years and it was probly one of the best new years I've had in a while. she's a friend of one of my close friends from my hometown that i have never met before. she's really sweet, nice, thoughtful and actually went out of the way to show interest in me. Needless to say we spent the majority of the night with eachother hooking up. We parted ways and we met up the next day in town and she slept over. we didn't have sex or anything because she wanted to wait. She lives a little less than 2 hours away from me and we met up for the 3rd time a couple weeks ago because she's going to be working going around the U. S for about 2 1/2 months. We had a really good date and we finally got to have sex. She complained a little about my size but was really into it as if she never had something like that before. Anyway my main question is that i won't see her until the begining of May, maybe sooner if they have a job by me. We talk basically all the time, phone call in the morning and when she finishes work texting when we both can. She talked to me about dating and I said we really should speak about that in person but I want to be exclusive with her. Before I said that thought she kept saying i can "do what i want" so i asked her out of confusion "you would be okay with me having sex and hooking up with other girls"? something I DONT WANT TO DO. and she got really upset and starting crying saying thats not what she wants and she wants me, i calmed her down and told her i really like her i just want to be exclusive and to talk about actually dating in person when she comes back for the summer. The company she works for splits the members into groups and she's in a group with two guys. It makes me feel a little uncomfortable bc im jealous they are with her for like 2 more months. She talks to me everyday and makes a point to, tells me how much she misses and wants to jus be with me, I shouldn't be concerned about the guys right girls?
