This story is unfortunately related to me .My gf also used to give non verbal sign but idiot like me unable to understand. Now she is married to someone else. I miss her a lot. Please girl avoid non verbal sign. Biologically guys in general find difficult to understand non verbal sign. Guys please increase the level of understanding, girls don't say straight forward .They will always drop hints. You have to propose her else get ready to regret like me which I don't want .
