Alright so I had been chatting with a chick from work who happens to be a mate's sister for a little while and while on a night out a month ago at a pub I had what I now realise was a clear escalation point which I did not take.
Then two weeks ago there was a work party in which we couldn't really talk too much due to us watching a show and whatnot but at the end of the night I text her saying that tonight was good we should hang out more often even just the two of us.
I got no reply or acknowledgement for that message and then the next day at work she was acting awkward and basically on complete ignore towards me although I played it cool and acted as if nothing had happened and went on about my business. Since then she has gone back to her more normal self and even hung out with me and a couple friends.

I seriously need some help with what to do with this girl. I clearly missed an escalation point where I could have k-close and then when I had made it clear for just the two of us to hang out, she didn't reply and went all weird. What should I do here?

Judging by what you explained, it looks like she’s spooked by your comment to “hang out more, even just the two of us.” And I would suspect that this might have something to do with her being your friends sister, thus the awkward manner as to which she acted in front of you.

OR shes simply not that into you.

You think her being the sister of your friend has anything to do with how she is acting?

I definitely wouldn't think that me being friend's with her brother (who knows im interested and is actually all for it) is the problem honestly, since at the party about a month ago she was definitely keen and i stupidly didn't escalate it.

It really seems more like I missed the opportunity and now she is kind of making me pay for it. She seriously went from so keen on me at that stage and even up until the message pretty much, so you wouldn't think the message was overly upfront or implying too much with how she was acting with me.

Not to mention that we see eachother a lot at work and in general and it has been relatively normal since the first day where she was awkward. I think definitely showing I wasn't awkward that day made it a lot better and now she is acting back to normal pretty much

Count 24 days when that escalation point happened. On the 24th day, shower up first and do some high intensity interval training either cardio or lift weights. Make sure you don't have any serious medical conditions. Note: shower before, not after.

Eat some steamed broccoli and cauliflowers or sauttee the veggies along with oysters. Hangout with her and escalate aggressively.

Most girls will be into you during their peak ovulation days and then ignore you like you don't exist after their peak ovulation period.

Soooo interesting night at work tonight where some random chick comes up and gives me her number. I will be seeing the girl I am into tomorrow because im going to be at hers with her brother. Should I bring up how this chick gave me her number tonight in conversation so she can hear to DHV? What do you guys think?

No. That's lame.

F-close the girl who gave you her number and then you turn her into your orbiter. When your target sees that there are other girls who are emotionally invested in you, then the competition will drive her horny. Competition will help you in closing the deal. DHV stories is like bragging. If you're not good at it, your sarge can easily go South.

Show. Do not tell.

Alright cheers mate, only problem is that this random chick is a 1-2HB less than my mates sister

Don't waste your time on girls that can't get your dick hard. She's also not good for social proofing or any DHVs.

Exactly so wouldn't be a better option to DHV by saying how she gave me her number rather than have her be seen around me because I can state she was a higher HB

I presume you are only sarging this one girl and you don't have enough experience in DHVs with, say, 100 girls. A poorly executed DHV can mess up your f-close. Don't risk it. Learn and practice the eye fuck instead of DHVs. The eye fuck is more efficient and easier to master.

Eye fuck literally got me past friendship with my current girlfriend. It's one of the most simple and ingenius techniques ever...

Focus on the Nonverbal Routine No. 1: Eye Fuck Escalation

In simple terms, look into the eyes of the girl and imagine having sex with her. Look only at her eyes and prevent yourself from looking at any of her erotic body parts like her cleavage or pussy mound.

cheers for the help fellas will give it a go tonight when I see her and see how it goes.

Just writing to update that I have been trying the eyefuck on her and so far it has worked to an extent. On a couple occasions when talking to her I have tried it and it seems to have done well due to her giving the same kind of look back (a different kind of eye contact than usual)

I am basically recovered from the missed escalation but back at square one. I just need another opportunity to escalate so I can take it this time
