Advice

I have a crush on this guy and sometimes he shows me that he feels the same way but I just can’t tell. We have an love/hate type of friendship but there’s also a friend that likes me and I don’t feel the same about him and I believe he’s getting in the way of me and my crush. I want to tell my crush if he feels the same as I feel but I’m scared of his answer. So can anyone give me advice on what to do on this situation.

P.s I’m not big on flirting or talking to guys so is him winking at me flirtation or no ?
