So this is my last exploit with a girl I was falling hard for in which the night I k-closed seemed to go well but got the LJBF through facebook and quietness a week after...

First time meeting her was at her house in which I ended up in after getting a cab with strangers for an after party. I went to see her band a couple of times in the next two months, going out with her and her friends another time. I got closer to her through facebook showing her music I made and we made a connection (I'm pretty shy and lack confidence in my tunes so this was a big step for me but she responded positively).

More recently, I got the impression that she like me and in the next two weeks we facebook/texted regularly, meeting up for coffee a couple of times. I then asked her out to bar where there was some music. I couldn't talk to her properly amidst the noise and the place was packed out which made the exchange so awkward. When we sat in a quiet, secluded corner conversation really flowed and I felt that sexual tension between us. She was reciprocating the feeling I felt. Alas, she worried she'd lost her phone in the bar too and thought she might have left it home. I thought this was a subconscious 'I want to leave' hint. So I took her back to hers, found her phone there, stood at her doorstep, felt the tension but nothing happened.

As I was leaving I sent her follow up text saying sorry for the shit night, we'll do something more conducive to conversation if there's a next time. She replied saying she enjoyed my company and had a good night. She must've enjoyed my company enough for the night to have been a shit one?

A week after more texting and facebooking (no phonecalls yet I should not), she invited me to her friends birthday BBQ and a night out after this. I was nervous as fuck but performed well; her friends enjoyed my company and she responded well to this. I arrived at about 6. At 9 she called me into a room. More sexual tension. She motioned for me to come closer and initiated the kiss. After about 10 minutes I asked "So do you want to give this a go?" thinking there'd been enough reciprocation to start seeing each other in some more serious capacity. She said she was apprehensive about liking someone at the moment, I said I felt the same as I hadn't been in a relationship for a while (truth is I hadn't been at all seriously). I backtracked and said 'we'll just see how this goes, as I don't want to mess up what we have'. I left to get changed for the night which was quiet pleasant from my end. I wasn't sure how she was feeling at this point and looking back something must've been off as I didn't spend much time with her when out. She kissed me as I left her on her doorstep at the end of the night.

I sent a follow up text 2 days later asking if I could call her at some soon just to shoot some shit. Nothing. I facebooked her a week later asking what's up and she gave me the LJBF routine which slayed me as she was the first girl I'd gotten to like on an emotional level and not for her looks though she was an HB9 in my eyes regardless.

This was two weeks ago and I'm still reeling a little bit. Using logic to get through this and stave off one-itis.

So where did I go wrong?

You went wrong at "So do you want to give this a go?".

Should have just let nature take its course and roll with it.

Just some personal opinions from an average joe here.. It seems to me like you're a guy who thinks very logically most of the time and while that's fine, saying things like "Let's give this a go?" and "sorry for the shitty evening" (even if it was) isn't helping you out. It might sound fine to you but i think what it projects is uncertainty, which is bad.

Like LBot above here says, try to let things flow naturally instead of trying to verbally make sense of what you two are feeling in the moment. Sexual tension is good and if you have it, you dont need to say too much but rather escalate comfortably.

Being friends with a girl is all good, but if that's not what you want i personally would just cut her some slack and not talk to her for a while. Show her that LJBF isnt what you are after. Meanwhile go about your business, talk to other chicks and generally be happy :- )
