radio silence

this girl works in my building. we have good banter but when it comes to the meet up she slips from my grasp. we make future projections but there is pretty much never a night she doesn't have a dinner, theatre, drinks etc she has a big network of ex uni and school friends and she self admittedly hates to be alone and so says yes to everything (except my cock!). we've often grabbed a quick drink here and there (before going on to do other things seperately) but never had a night to ourselves. i am trying to be patient as i think my impatience has fucked me up before, but i also want to strike when it's going well.

i thought this was one of those weeks

eg. after a week of flirting, me being somewhat aloof (yet sexual) her seeking me out, we had a quick drink after work on tuesday (throughout this brief drink she is constantly playing with her hair and jewelry, laughing at every dumb thing i say and responding to flirting and touching with smiles and blushing) and then she has to meet friends for dinner. it's on my way so we carry on talking (a bit deeper now) and walking and i drop her off. an hour or so later she texts me "thanks for walking me!! X"

she never usually texts after we've hung out, especially something that isn't a big deal. all the signs seem to be there. i text back "it was my pleasure x"

next day we text:
her: (something about the place she went to dinner)
me: (picture of my first ripe tomato - i've grown these mothers from seed - she looked after them for me while they were very young and i was away fro 3 weeks)
her: oh my god! we'll have to have a tomato party to celebrate their birth x
me: well you had a hand in that x
her: i was like their mother for 3 weeks x
me: and i provided the seed x
her: and now look at them x
me: i have to go now, this conversation is turning me on x
her: ha! x

on friday we saw each other briefly in the morning and chatted about some exhibition we'd both been interested in that was ending this weekend. i have a card that gets me +1 into all exhibitions at this place and she knows this. i suggest we go that night. she says it might work but she's been out the night before and is craving sleep.

i don't see her or hear from her again that day, so after work i send: "had to run.. (exhibition) tomorrow, though. call me when you're up x"

no response that night or the next day.

now i don't know whether to re-engage or if that's just the needy impatient part of me and i should just shrug it off and wait till i see her next week. pretty bummed she didn't even bother to say no.

any insight/feedback much appreciated.

(i went to the exhibition anyway)
