Search Results: signs of cheating girlfriend

I sit next to this guy in one of my classes. He's very attractive and very nice. We usually chat before class and stuff. We are also doing a semester-long group project together (with a few other people) so we exchanged numbers. A week ago, out of the blue, he texted me and said that he hoped I had a nice day. I was very confused, wondering if this was flirting or if he was just really friendly.

So I respond back, and every since then we've been texting. I've never instigated the texting, it's always been him. He texts me after our class together and tells me he hopes that I have a nice day. He's told me that I looked nice, sent a couple winky faces, and some other various flirty texts over the weekend. All signs would say that he likes me or he's interested.

But then I go look him up on Facebook, and there's another girl in his picture. Turns out, she's his girlfriend. When I click on her profile, it says she's in a relationship with him. I am beyond confused. I feel really uncomfortable now knowing some of the flirty things he's said to me.

I see a couple of potential things going on here. They either broke up and never changed their profile pics or status, he's just abnormally friendly, or he's sort of cheating on his girlfriend with me.

What am I supposed to do about this? I don't want to be the "other girl" and I'm not sure I want any sort of romantic relationship with this guy.

I`m kind of torn here see my boyfriend went on a trip to Seattle and I ran into some of his friends who I guess as they put it find me beautiful and claim they love me its only three of his friends and he has a lot that I`ve met when I ran into them they wanted to buy me a drink and kept saying things like your beautiful I love you now I just told them I am with your friend and I don't cheat and now he has one friend who's actually the reason we met again since I`d met my boyfriend through a friend of mine he drove me home one time and I thought he was cute I just was to shy to ask him for his number but when I went to hang out with another friend of mine only a couple weeks later he was with him and this time I asked for his number as I took this as a sort of sign that I should this friend of his said that my boyfriend is his best friend so we can't do anything at least he thinks that way the others seemed to understand as well I think but its happened a couple times now my boyfriend introduce me as his girlfriend to them all so I thought they wouldn't even think of it I just don't want to be the bad girlfriend who says it to my boyfriend and have anything happen with his friends and him but I don't want this to always happen I`m ok with making nice and being friendly to his friends but not cheat on my boyfriend as I know what its like since my ex cheated on me with my best friend so I would never wish the pain of that or similar on anyone else what should I do?
