"I dont like you, in fact I am disturbed by your presence".
You said you want to let her down gently, so do it, "Awh gee wizz Im not really looking for anything golly, was a hoot 'n a holla meetin' ya ma'am".
The real problem is you're 'dropping in' for some situational advice, well sir, its not like that, you have to fix your whole being on it.
You said yourself you are at the bottom, so fuck her, literally, tell her to meet you and bang her. Go out and start your journey, go speak to girls in clubs or wherever and go for it!!
Read good books and information about dating and
PUA to get your head around it.
