QFT.
While I am no professional at relationships by any means, the number one reason that they have failed in the past is due to being too needy. I obviously have no idea about your past or current relationships but proving you are capable of being fine by yourself goes along way with girls. Try to keep it as casual as you can and let things progress from there. Relationships are a fickle beast, keep your head up and things will get better. Best of luck man!
