I feel OP just don't make these mistakes again..
I remember I was macking on a shorty and while on my break I was walking with her to her bus stop go home...before I walked off I put my handout for a handshake
She went
"What no hug?

"
The next day she hit me with the "I have a boyfriend..you're not my type at all"
She worked in my building so I saw her everyday...only thing I could do was hold my L...kept it cordial with her but didn't go out my way to give her attention
She had a bad little samoan shorty friend who I would always talk to..one day I was talking to her in the coffee shop ole girl worked in. Ole girl was jealous because I wasn't all up on her..stepped in our convo and everything
Alot changed since then and I got my confidence up..and I can tell I intimidate her now...
That nice guy shyt does not work....especially when they find you attractive..it frustrates them more because they expecting you to be the confident playa.
