For what it is worth here is my take on Lee.
He resembles (not literally) a over zealous puppy dog, eager to please, desperate to be liked and loved but extremely irritating, very inappropriate and high octane attention seeking.
His intentions are not bad, he doesn't have much self awareness and pretty much zero self confidence. He is overcompensating for all of this with his behaviour and is genuinely really upset at how he is being perceived. That may be hard for many to believe but he really has little idea of how others perceive him.
He lacks the ability to inhibit so everything just pours out, every emotion becomes jumbled and meltdowns such as the ones we have sadly witnessed are common in his life.
The story of how many women he had in a week was so long ago he thinks his age and innocence is excusable. However he doesn't realise most people would be shocked at this admission. His honesty is childlike. He is childlike.
Whilst he is extremely creative and clearly longs to be loved he emotional quotient EQ is that of a 7yr old. He is intelligent but just not socially aware enough to keep himself out of the limelight. He doesn't have a great short term memory and gets easily distracted, his concentration is poor and he forgets what he has said and to whom. That also gets him in some sticky situations. His brain seems to operate at 1000mph and he just 'blurts' out stuff in an attempt to pacify and please others. He hates confrontation although provokes it unknowingly!
If Lee was with people who could guide and inform him he would be fine as he is keen to learn but whilst he is with women like Luisa, Casey and Jasmine who also have little self awareness or perception of how others see them or simply they don't care he stands no chance. They are so NOT the sort of personalities he should be surrounded by!
I don't think Lee knows who he is to be honest and the bit he does know he doesn't like.
Just my opinion before anyone shoots me down in flames!!
