Soul ties

Let me just start off by saying how real this ish is.. my ex and I were together for 5 years & he’s recently done me dirty and has been living with him mom. As our relationship has been on the rocks he decided it would be a great idea to go have sex with someone else AFTER 5 years!!! Still asking me to come home!!!! Has lied about it & the only reason I found out was thru his friend. Anyways, I don’t want to be with him but I still am looking for answers even though it isn’t gonna chnage shit for this situation.. Idk why I seek these answers but I do whenever we talk & i have to remind myself what is this gonna chnage? He’s a liar, a cheater & sneaky. He doesn’t have loyalty for himself he’s not gonna have it for me.. why am trying to look for closure? 😒
