Don't lash out,man. Don't do it. I know it sucks when a girl gives you a lame excuse,when you already know what she's saying isn't true. Another thing you don't understand is that by you lashing out,you are doing two things at once,and both of them are bad for you.
Number 1:You are burning bridges. Look,I've asked out women before,and they said yes. They said yes,and then we didn't go out.
I've asked out women before and they said no. They said no,and then we did go out. Women can be some unpredictable creatures,man. So don't lash out/tell them off. I can assure you,that when they see you act like that,they're saying to themselves,"Wooooh,that was close. I'm glad I flaked now. What a temper! I'm glad I found this out before I got too involved with him".
Number 2:You're feeding her ego without even realizing it. When you lash out,you're expressing anger. When you are angry,that means that you care.
When you care,that means that your emotions are involved. If she finds out that you care and already have emotions towards her without even having been on even one date yet,game over. She'll already have what she wanted from you. It's the same thing as when a nice guy tells a woman that she is beautiful or hot,or tells her how he feels. When she learns that a guy already likes her without her having to do anything,she immediately losses interest.
