long distance relationship on space time

okay well we were in a long distance relationship for 4 months and have been going on space time for 3 months. when he wants he avoid me and doesn't reach out to me 3 to 4 days then text s me like nothing. sometime i don't answer or respond cause it toke him long to reach out. he is always thinking im seeing someone and etc. which is why he had asked for space in the 1rst place. its now going on 3 months so i finally said if either he wants to work things out or he doesn't I'm not going in circles with him any more so what does he want to so. he responded if thing can get better but if they cant then no. that to me is so obvious. i responded well we can try and if things don't work well it just doesn't work. he then text me the next day saying he fell asleep and i text him if he had an answer to my question, he never responded never called me til 3 days later he text then called . i didnt pick up , didnt want to speak. i called him the next night he was really quiet i was like maybe is a bad time he was like i been calling you dont understand why it toke so long for you to call , were u sleeping. i was like no i saw you called i didnt want to pick up because i was upset that it toke you so long to respond. he said he had text me back and responded to my text. and for me to stop insulting his inteligience he already knows what i was probably doing .. he said i was out doing me. i was like listen you need to treat people the way you want to be treated . i feel i have been accessible for you and whenever you want to avoid me and call me 2 days later you do and when you reach out to me if you cant then its a problem where you think im seeing someone.

hes like please dont act innocent i already know your a different type of girl now.

but honestly how would i be the same with him when he treats me different.
he has his insecurities with or without me....

i dont get it....
