Ive been texting with this girl for about a couple weeks. Shes already told me things like "you make me smile" and she even asked me to send her a picture of me. I told her that I was gonna go shopping for a friend of mine for his bday and get him a shirt cuz he still wears his middle school clothes and told her she should tag along help me pick something out. We decided on Sunday and to maybe go bowling afterwards and this morning i sent her a "get excited for tonight nerdball" and she responded with what time again and then after I told her she texted me back " My family is having a cookout to celebrate my grandparent anniversary tonight and so I dont think ill be able to go " a few hours later i shot back with "just got my buddy a blue v neck shirt hope it works & no worries just dont leave the meat on the fire too long we dont want any accidents!"
How should I continue when I text her again and any advice on reducing yet another flakey response on a future meet up? Seems like shes into me and she even says to visit her at work (which I usually tell her I cant make it) but then she flakes so how can this be salvaged and any advice on preventing future flakes?
