Ladies please help, Why she texted back... yes sir?

Anonymous
Female I was close to things happened I stopped contacting her. During that time she was telling bestfriend how she think about calling and texting me. So after not texting her for 7 months I contacted her. We talked she texted paragraphs and told me how she been busy lately. This might be the reason she texts hours at a time. But I told her I miss her and I think our bond/friendship would be stronger now after the things we been through... all she texted back was "yes sir, are you doing alright" she confirmed he was right. But through text after I told her how good my life has been she seemed less interested. ... but what do you think about what I texted her and her reply?
