Search Results: how to know when she's flirting

(I don't live close to him, basically long distance) He:
Flirts with me
sexts me
talks about life with me
call me (Babe, babygirl, cutie, bae, baby, "cute"cumber) but basically never by my real name
tells me about his life and passions and asks me about mine
compliments me and tells me I'm talented and smart and stuff
calls me bro and dude but tells me not to friendzone him
argues with me and jokes about stuff and we rant together
acts jealous when I joke and say I talk to other guys, and tries to make me jealous (we act all jealous and he's like " I'm gonna kill you, I'm you're only hot guy :( "
But from what I know, he actively texts 2 other girls (3 including me and basically does the same thing with them but he never told me about it, I found out on my own)
He gets actual nudes from them (I don't do that kind of sh*t and he knows but he "accidentally" sent me a dic vid in the 1st place anyways)
Doesn't talk to me everyday, I guess he doesn't want to talk to me everyday. But he texts other girls and replies days later saying he was busy

Please read the whole thing!!! We both are high school sophomores. He was and is in my PE class. He is a smart boy but really shy. I could say that I have never seen him talking with girls (Before/ after school, lunch and in PE). He would only answer the question that a girl asked with a really short sentence and doesn't continue the conversation. That's all I have seen him interacting with girls in these 2 years so far. Because of those reasons, I am pretty sure he doesn't have a girlfriend. On the other hand, it's hard for me to talk to him since I am also a really shy girl who doesn't really talk/ flirt with boys. In all of these 2 years, we only had 3-4 short conversations (he starts all of those first). When we are talking, he seems to try to keep that conversation going on forever; he looks into my eyes and smiles brightly. I have never seemed him, looking into a girl's eye and smile like he did to me. Even though our conversation is only about a minute or+, that's the longest time length that I have ever seen him talking with a girl. He stares me a lot but he looks away quickly when I caught him staring at me. I am pretty sure that he caught me staring at him a lot too. I don't know any of his social media acc. I heard that he doesn't use Instagram, I saw his acc name on FB but that acc doesn't seem to be active anymore. All of those things seem to be pretty positive but there are also things that get messed up. He gave me that big eyes surprising looks when he saw me in the passing periods. He tried to go the other way after he saw me several times in the hallway, tried to go to the different places after he saw me in the same place. I think he tried to avoid me. He is never changing and always the same. What should I do? Should I keep crushing on him? IS he like me? So Sorry for the really long paragraphs.

My boyfriend has never done this before
So yesterday i saw that he commented on this girl's picture on her instagram
They know each other from high school
He commented on one of her pictures saying "wow you look amazing, looking stunning for a mother"
And then i confronted him about it
And he said he didn't meant to flirt with her but he kept apologizing to me... and that he would never do it again... and that he never commented on other girls pictures ever since he was with me... and that he realized it does sound like he was flirting with her.. and he realized his mistake and telling me that she's married with kids and how he would never date a mother... bla blah blah
And then i tested him and said "ok.. unfollow her on instagram and delete her from your instagram"
And he said "shes a high school friend.. but ok" and then he deleted her from his facebook and unfollowed her on instagram infront of me
If he wanted to be with her, would he unfollow her and delete her?
I was swearing at him full on non stop (calling him a dickhead, prick, idiot, etc) but he was calm and patient during the confrontation and he kept trying to calm me down..
Oh and we have been together 1 year

Let's say your mom gained weight and got wrinkles. Your dad tells your mom she's ugly as sh! t and that if he knew she'd get ugly and fat he would of never married her, and would of been left. Your dad also tries to get plastic surgery for your mother, get her to wear fake hair ( he doesn't like curls) and shows her pictures of female celebrities that he finds beautiful and attractive. One day you see your dads phone and you see that he's flirting and sexting with a woman from his job. He also is trying to get her to show him nudes but she only gave a boob pic. - Would you still love your dad if this was how he typically treated your mom?
