Will he come back ?!?! [plz help dont be mean either im hurt thanks :(?

I know this is alot of info but please help if you can..Im a leo woman. Hes a libra male. We both have been dating since we have been 17 we are 20 now. Im dominating and hes sweet loving and sensitive. He has broken up with me 3 times over the course of 3 yrs and came back on his own. He gets UNDECISIVE when we go on for weeks with constant arguing and bickering over petty things. First two break ups i was too much of a ***** and he left and the third one he had his guards up and we couldnt stop arguing. We have had beautiful moments ofcourse. He says he loves me he just cant take the constant crap. The longest break up we have had is four 3 months. I know some of you will be like move on its to much or something but please im looking for true answers. he has been confused for two weeks now I even BEING A HOt head took his attitude and pledged to stick by his side because ONCe again he felt distant because of the contstant fighting and i asked him last night if you want me to leave ill leave hes like i dont know i dont know if i want you out of my lfie im just so stressed all around and this isnt helping. We got in an argument im like ok so what should i leave hes like yeah fine thats fine tc im like ok so ur breaking up hes like yeah ok. Then i texted him im like ill be here for a bit if you realise what your losing and wanna come back. (plus he has a phone line he gave me) and i said ill carry the phone untill he disconnects it. I wished him luck and told him eventually ill move on but ill be here for a bit. HEs like YOUR saying all this to get in my head this that im like no its from my heart. He called i ignored him becasue i was crying :( i texted im like i said bye and he never called or texted back. Im afraid he wont come back now...:( you all think he will be back or is he gone :( he never even said bye :( i just have his phone now and im scared to look at it thinking maybe he will disconnect it :( Everytime he wants to leave i convince him but this time i let him go...help me please :( Do you think he will come back again...if so when do you think?...thanks guys!
