yesterday after a month my ex has messaged me...he wants to come back in my life and now i am having mixed thoughts....there are many reason why we broke up...he didn't use to give me time ..and had prblm with my guy frnds who i knew before him..but used to check out girls even when i was with him and whenever i used to ask he just blamed me for each and every happening..the reason he told for not talking to me was because i just argued with him too much...then i stopped arguing but then also conditions were the same...it destroyed me mentally ..i broke up because i cared about my mental health..but even after the breakup his thoughts are hollowing me from the inside....should i return to him?
