The sensitive guy mode is very hard to fix. If she labels you a 'Nice guy' it's very hard to remove that. You also DON'T want to be a jerk at all - never.
It's kind of a fine line between both.
I've said to girls early on - I'm not your therapist and I'm not your girlfriend - please go talk to your girlfirends about this. They really don't want to share this stuff with you anyway - if they do - back off.
