I feel like I'm a rlly bad person

So I used to like this boy in my yr fir like a week and didn't tell anyone then my friend started liking him an told me and our other friends. I told myself to back of and I went without liking him go a yr.

My friend still likes him and over the summer I kept thinking abt him. Now all of this week everytime i look round hes staring at me like looks me in the eye. So I told my friend that and shes in complete indenial that he was but I definitely know he was like eye contact sure.

She said she didn't like him yesturday so I began to accept to myself that I did like him then right as I was ready to tell our friends that I liked him she says that she likes him.

All of this past yr I've been making up crushes and I feel like km going to betray my friend if anything does happen between me and him

What do I do?
