Search Results: liking a guy with a girlfriend

Hey guys, it all started last year in July
So I was bad in history and I needed a tutor turns out there was a guy called zach he studied in the school I am studying he came to help other students with their studies I actually liked him the time I saw him he was tall and had this bass voice every girl at school liked it, so he became my tutor he came to teach me at pm till dawn because we were staying at school camping
So I started liking him and turns out the feeling was mutual he told me that he liked me and all he started saying I'm his girlfriend
He always tell me I'm beautiful and he'll never leave me for any other girl
But the fact is that I agreed back then I was a little dumb? I don't know but rn I don't wanna be in a relationship I don't talk to him these days because he thinks I sold my phone and now I'm ( phoneless)😂 but I don't wanna be his girlfriend anymore how do I break this up to him
I need your opinions guys

This has NOTHING to do with my other questions, i just want to know your thoughts!

... If a guy (with a girlfriend) constantly stares at the same girl & shows signs of liking her etc.

There's this guy I know from work. We never met outside of work but we haven't known each other that long.
He always spends breaks with me. He randomly stands next to me/my desk, while talking to other colleagues and he tells me about his secrets, aspirations, fears, his family, his childhood... And we often talk about our families. He even flat out asked me, if I'm taken, even though he should've known. It felt like him trying to be absolutely sure.
He makes sexual jokes but rarely.
He stands very close to me, usually a lot closer than with other people.
Other people have started teasing him about liking me. He usually blushes and doesn't really say anything. He just tries to change subjects.
Sometimes however he points out things like not wanting an older girlfriend (I'm 6 years older) or that he never had a real long term relationship. That's confusing to me.
Does he have a crush? Does he want to be friends?

I know the question might sound a little ego filled but I am dumbfounded on how guys tell me they like me so quickly. I will be talking to them for a bit and couple weeks or days later they are asking me to be their girlfriend not even hinting that they like me just will you be my girlfriend. And it puzzles me how they can fall for a person so quickly. Is it really cause they like me and my personality etc or are they just wanting a girlfriend and any girl will do. Guys liking me is a very new concept for me so I don't know what to think. Do all guys do this or move that quickly?

I will be honest and say I do think I would be a great girlfriend cause I have a lot of good traits but I don't think guys can fall that easily for a person and be genuine about it.

So this guy who asked me out when I was new to school 3yrs ago and I said no but then started liking him and we were friends. He gave me his # at the end of the year too. We had no classes and never talked ever. I texted him like 2yrs later and then again (no answer) this summer and confessed that I liked him for this whole time. He snapchated me asking about it and told me “he had a gf” then I told him “I didn’t want to date him” and he was like “welll” and I tried to say I wanted to be friends. I said “I love you” cause it was on my story that the 5th viewer I had to send that. Even tho I told him he saved that one message. Anyway he’s in one of my classes this year for the fist time in 3yrs and he looks at me and he’s touched my hand a couple times and talked to me and said “I’m so smart”. Also in the hall when he’s with his girlfriend I feel like we always look at eachother. When I had a boyfriend my friend told me he was STARING at us for a while. He also always sits at the lunch table near mine. I don't know but it’s weird.
