After spending some time reading these posts and inboxing a few ppl. I can see why there is some struggle. So I have some suggestions worth considering for successful meet ups. 1) Be clear with what you're looking for or seeking, 2) accept your issues and own it (I.e. introverted, low self-esteem, etc) and 3) Be truthful and open minded.
Healthy personalities may equate to healthy friendships. Trust me.
