Search Results: i'm dating two guys

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?

Gonna give long story short:
-Met girl off dating site. been talking and hanging out every so often for 4 months so far.
-A month into talking to her, things slowed down drastically, when I upfront asked her whats wrong, she told me she doesn't want a relationship. I upfront asked her "Be honest please, i won't be offended, do you just not like me?" and she said "I do like you im just not sure about a relationship right now". and yes i did ask if there's another guy, about 2 times and she keeps saying no (and doesn't get defensive)
-As i stated before, even tho she told me she's not ready she still hangs out with me and we still go on cute dates and cuddle and stuff

Everything was fine untill I saw a comment that bothered me. She knows I know her tumblr, as she's shared it with me and I've sent her cute stuff on it sometimes. However she doesn't know I know her instagram (to be honest, i just googled her name and it popped up lol)

here's what got me paranoid:
-------------
She posted a selfie today (on instagram) and one of her female friends commented "Haha damn girl lemme hit that, kevin doesn't have to know" (my name isint kevin, and i haven't met her friends) and she replied "of course you can :)" ( referencing to her female friend)

I noticed that kevin liked that selfie as well as other friends, and i checked out his instagram and she liked some of his photos about his job.

when i went to his Facebook, it said in a relationship for the past 8 months. what i also kinda see weird is he has a "life event" posted that says "met (girl im datings name)". that doesn't necessarily mean dating or romantic wise, still kinda weird

-----------
the only thing that kinda assures me that maybe im overthinking, is 2 things. one she told her parents about me. not in a bad sense of course. and two, today i told her "You know, sometimes i feel like you just want this all to end because you still barely talk" and she replied "thats not true"

Please help GaG!
