What to do ?

have been dating this girl for 6 months and we were in fwb before that for 1 year . What annoying me is told me she always had crush on me n she wants to talk to me all day and text me about every stuff I might b doing , I obliged , I would never leave her on read , she works 5 days out of 7 , she would take time to reply sometimes 2 hours it's annoying when you want to have a conversation and she she is texting after 2-3 hours , I told her for God sake I want to have a conversation where we are reply instantly not waiting for hours I would wait for weekend so we would talk at least in ight if not all day but on the weekend she would seldom msg n say she was busy and in night she would say I fall sleep I would wait patiently she would then say her relative said something she didn't like and left me on deliver whole day and night I would wait for next weekend and same thing repeat...and Have seen online past 12 am so many times ,
