hmmm, now take into mind im not a 19 year old girl but ill do my best to give you my honest opinion.
it could be a few reasons.
-she could have those afternoons free cuz she is plannin on seeing him. but she gets bored. so she starts texting ppl. you included. on the days she doesnt text ya. she is keeping busy somehow.
-she could associate you with him somehow. so everytime she is getting ready to see him or knows she is seeing him. you pop in her mind. so she has the urge to talk to you via text cuz its the fastest. she may associate you with him in many ways. he may be missing something that you have. or she may be thinking, hes leaving soon. who will i fall back on? etc.
-or obviously she has some sort of feelings towards you. not love. but an attachment of a kind. so she may be on the fence in a way. she has feelings for this guy. but you were in there first. so when she feels the feelings towards him (thinkin she is going to see him) then the feelings that she has for you surface and her mind plays games and the games come out as a contact.
- she may be trying to pull away from him. she knows he is leaving. she knows she will not be with him. so she still has strings attached to you. she cant pull those strings free. so when she gets scared she pulls those strings tight and gets you close.
on the days she doesnt see him, she doesnt feel those feelings of pulling away from him, cuz her mind is elsewhere. (work, school, family)
but on days she knows she is seeing him. they all pop up
-or and this is my favorite. shes coo-coo and you need to cut her off
