Would you say my ex may still answer my text???Do i stand any chance at all(he's 27- im 18)?

My ex and i broke up 4 months ago.İ was incredibly heart broken at the time and acted without thinking.İ bassically harrased him with texts and calls and only recently stopped.İ still harbour a lot of feelings towards him.He is 27 im 18.İ sent him this very last text an hour and a half ago;

İ miss you.İ know the way i handled things was atrocious.But to be frank i was at a loss.İ still am.İ could really use your friendship right now.As just a friend, i could really use a friend who isnt 18 right now and who doesnt hacve the mindset and feelings of an 18 year olds.İve come to realize i need to work on me, my self confidence and my self respect.İt seems both are dangerously low.İ think for years now ive been so buisy being there for my mum that ive neglected myself and even become like her.İt sounds like im trying to guilt you into a friendship-im not.İm well aware that u harbour a lot of ill feelings towards me and the shitty part of it is that its my fault cause i kept repeating my mistakes over and over and over again with you.İ really hope u'll consider this.İ really do miss u, talking to you.You have a way of calming me down and relaxing me.İ know that the way ive acted has proven to you that im not as mature as u thought i was in your mind.İ hope that u can see past that and someday realize that my emotions took over me and i really wasnt in control of myself.İ hope ur doing ok, and that ur not cussing myh name right now.

İt has been 3 days and he still hasnt replied.My phone says delivered.Which means his phone is on so he has probably seen it by now.Why dont you think he has answered me?Do you think he will answer me?Do you think i stand any chance at all?Do you think he will give it a couple of weeks and then answer me?Do you think he's testing me to see if i will keep texting him?
