Saw a male coworker getting close with her and I feel like a loser now.

I wasted 2 years being limerant to her thoughts of us. It was always me, who initiated, despite being a quiet man. She'd wave, smile and walk away at work.

I tried last 6 months pretending to be busy whenever she walked by to see, if she will stop to chat, but she didn't.

New male coworker has been approaching her, saw maybe him asking her number as they were looking at his phone standing sideways. He's been finding more and more time to spend with her approaching her when she's alone to chat.

I can't believe, I feel like a loser comparing myself to another man, who went after what he wanted. I was never confident and missed my chance, wasred 2 years of my life /mental health with her 24/7 on my mind, feel jealous, insecure, and hurt with thoughts of them together.
