Should you confront a guy you valued (childhood friend) who led you on in he past/ made you think he liked you?

I feel hurt bc I never felt good enough for him and everyone said I wasn't his type etc. I feel bitter bc I think he is attracted to a girl who really wasn't my friend. She was just using me to get to him and tbh she was very competitive with me and I knew she didn't really like me.

I think he may actually be attracted to her bc he's a confident/(playerish) guy and he kind of acts different when she's around. He did reject her in the past but maybe he changed his mind.

I guess he does like her cause I got led on and she didn't.

I feel depressed thinking about it. I dont know why this hurts so much.. I haven't ate in 4 days and all I want is alcohol. Im also having other issues on top of this. But i just feel undervalued and made to feel that my feelings dont matter by someone I thought cared
