Did I make the right choice?(little long, but please help)

Okay, so i was with my ex 5 times from may 14 till august 6th. Now my recent relationship lasted one day, yesterday till today. I broke up with my bf with whom i had a long relationship for this new guy, the new guy has known me for almost 7yrs, n we liked each other for almost 6yrs, n then i broke up with him today, he wont talk to me, did i mae a huge mistake? also the guy i went out with longer i didn't meet till april, plus i want to be with the guy tht i just broke up, can u tell me what i did wrong and how i can get my recent ex back:

heres y i broke up with him:

i called him alot today, since he wusnt answering, he fnally answers tells me to call a diff number, and his older bro piced up n said stop calling ur not allowed to call him anymore, so i told his bro to "tell him its over" n well his older sis calls me n im like arnt i spossed to not talk to u, i hear her mom in th backround saying i can call just not as often, so after she gets off the phone with me i sent a text saying from now on call me
