hi, I met this girl at work and we've been friends for a long time and been flirting regularly.
today i was Texting her and this is how the convo went

Me: hey sweetie
Her: hey, whats up
Me: nothing bored and you?
Me: do you work today?
Her: nope hanging out with my friend farah
Me: is she cute?
Her: yeah shes a babe shes from egypt
Me: oh that sounds like my type of habibi my albi
Me: is she single?
Her: no lol shes pretty much married
Me: Pretty much doesnt mean yes theres still an oppotunity
Her:no trust me theres not. shes locked in
Me: are you locked in too or is there a chance?
Her: Im not locked in lol but im not looking to date too busy with school and work
(I thought this meant rejection so i played cool and backed off)
Me: I never said i wanted to date
Her: so you just want to be friends?(this msg mind effed me so hard. what do i reply to this? she rejected me and when i backed off shes not happy then either)
should I be like "depends how you define friends?"
what do you think I should say here?
