Search Results: girls acting like their friend

I'm trying to comprehend what happend in my class yesterday. There's this guy in my class and he's always talking to this one girl (I thought that they're just friends). She often dresses really slutty and he's always acting really like "on edge" around her or something. So anyway, I saw he was talking to her and while he was talking to her he was touching himself (?) and I was like "huh, well that shit does not normal". Yet she still continued talking to him after that, the fuck? Later at the end of class I saw he was looking at porn (ew) on his phone and he didn't seem subtle at all about it then he just pulled his phone away really fast bc he saw I noticed. Are they like hooking up or something? Bc i know he has a girlfriend (Idk if theyre still together), and I thought that girl thinks of him as a friend but she looked heated or something. What do you think they're relationship even is?

We met on a Facebook page group, we start talking. I develop my feelings to him and after 3 months he confessed he loved me. We've been texting, voice and video clips together. I never met him because we are in a long distance, I live in Asia, he lives in Europe. We've been talking for a YEAR. We always wanted and dreamed to meet up but it takes a huge cost and we're still studying.

We've been very close like we talk everything, we share everything, I didn't know that we've been falling inlove to someone I didn't met in person and I feel that he love me. But the time goes by, he became cold. Like our relationship is gone, we don't text too much before like all day, the sweetness is gone. I saw him commenting on a girls photos, he sends me girls photos or their conversation like he really made me jealous.. and I feel cold too. I try not to talk to him, but he keep messaging me but not upset like he did something that hurt me.

I can't resist talking to him, but I know that talking me first is his one way to keep me calm. He still send me photos of him and his activities, he's updating his schedule to me.. But everythime I confront my feelings, he always says that he move on from the past and he feel like we're just Friends and acting like there nothing happend in the past. I feel really hurt. But I know that the old him is still there and he just don't want to admit.

Until I can't hold up anymore I tell about my feelings and he acts that it's just in my mind, that I think too much. he just even said that "we" both move on. Until the argument getting worst, he unfriend me.
I told him not to do that. I want to beg him not to unfriend me but he even said to me that 'I don't need him' I love him so much, but I think we both need space so I let him do that and I'm just been broken.
