am I wrong?

So my problem is that i get bored of people easily. I can’t love someone or give someone a chance in relationship, because I always think, that , they may not be the one. So one day my friend said: ,,u are evil ! One day u will get karma ! why u give people hopes ! u know they don't look at u friendly way “ .

Thing why she told me that was because i have lots of guy friends, who are attracted to me and when they confess Me their feeling i always say: no

is its not my fault i look at those guys as my friends or someone who i would love to be friends with. i cant look at them more then friendly way… at first i may like them but when it comes time for me do decide if i like them or not… i tell myself: he isn’t one for u .thing is I never understand when i love someone, because i am always afraid that they aren’t one for me. I struggle with overthinking such as:what if u will get bored with them or what if u will fell in love with other person. I want to change I really do i want to understand who is right person for me or who isn’t, thing that i cant do that which makes me feel like a player. Please can any of u give me advice to how remove this thoughts from my mind?
