I think i missed my chance at love

I don't think I'll ever find someone who loved me as much as she did.

It's hard to explain this but to make a long story short when I was younger I meet a girl who loved me unconditionally and I loved her back in a similar way.

Problem was she was very social and I was super shy she was ok with that but it was hard for me to express myself and how I felt.

So she ended up thinking I wasn't interested and moved on it hurt me deeply and when asked by anyone about it I say that I have moved on.

But a part of me still misses her last I heard she was married and has kids and so far I've been unable to find anyone who truly loves me like she did.

Is it normal to feel this way?
