Is it ok to repress thossle feelings i have and do what a sane mind say is better?

6 years ago i crushed over a guy, will alot but didnt have the chance to know him, so 4 years later whenever i see him i feel happy and like i can read through his eyes, i made a move , at first he was happy and said that he thought that i would never want to talk to him but he acted hot ans cold and eventually things ended up and he did say again "u dont want me u deserve a better person,, i knw but u dont" and later he had a gf.but i really adore him i see alot of things in him amazing and feel theres smthn mutual.another guy , who has been a friend for long, we lived in the same area , same uni, many mutual people , he is my friend's brother so he was like a brother to me and my sister too,, a year ago will he's been hittin on me , before he didnt this much and i do recall before that he used to ignore me for other girls sometimes,, so we this year we got to knw each other even more , he is the only the guy friend i feel safe with, guess bcoz he is my frnds brother , anyways i think he took advantage of me , it ended up us making out and talking openly , but the thing is he is having an almost 2 yrs gf. so i asked if he loves me , he said i care abt u and like u bla bla but not really in the serious romantic way.i felt rejected but i acted cool and like i just asked the question of curiousity. third guy, well long time ago he was a girl i knw's bf.she married another guy , so hes been hittin on me since, that was 2 yrs ago,, but i was so cold since he's the kind of guy who.is not direct.and to be honest am not attracted to him much, i dont feel happy when i see him or talk to him, even he sounds the 'i like this , i dont like that, do this, dont do that type' im not loving the way he thinks either,, but he is capable of getting married as he has a great job position and good financials,, the other too are still juniors probably havnt found a job yet.most of girls my age r getting married, and.my mom.keeps nagging about the subject.wht to do.i keep rembrn da 1st
