Should i take him back after all this...?

so me and my ex knew each other for about 5 months but we only dated for exactly 2. He wanted me sooo bad from the beginning and I wanted to be friends. I didn't want him I wanted my other ex bf, my first bf.I was hurt when my first bf broke my heart and was ready for another relationship tho he kept insisting. He said he'd nvr leave me, nvr hurt me, that hes been down that path and would rather see himself get hurt than hurt me. He wanted to take care of me I was amazing and so much more....After hanging out with him over and over again as friends I started to rlly like him. We eventually were together and things were good. Things got pretty bad when my first bf showed up at my work with his new girl waiting in the car... I told my bf at the time that i wanted to smash something going on about it and how he was trying to make me jealous. I regret this so much but i just wanted to be honest. Throughout or relationship he told me he loved me multiple times during the day and then one day it stopped. The day i confronted him bout his change was the day we broke up, on our 2 months. He said we had lil in common that he need to go out with a collective group of ppl to dj, umm that he fell out of love with me, and that he stopped missing me etc... Then just yesterday after not talking to him for over a month he messages me saying he regretted breaking up with me, missed me, should have nvr done it. He asked me if i still had feelings for him i said thats a very complicated question cuz it is part of me wants him back but another part of me wants to tell him to fk off! Was his djing not cutting it for him and he got lonley like he said so he wants me back? pfft. unno i just don't know what to do i'm goin crazy cuz I cared so much about him and now I'm wondering if i should give him a second chance or not? Some advice please. thanx!
