my ex

i feel so bad my ex texted me saying he will always be here for me and he still loves me and i texted him back talking abt how bad he treated me and stuff and my bf now is great but can be controlling and doesn’t listen to me a lot, but i don’t think i’m gonna tell my bf because their just gonna get in a fight about it and then he’s gonna be yelling at me and i’m tired of it. please tell me what to do but don’t make me feel any worse about it because it’s to late now.
