Disappointed

Hello girls, I am in a really stressed shape, I am just about to break up with my boyfriend (we started TTC this cycle) cuz I found out he is still cheating on me and he acts like he doesn't give a shit about me but he don't want me to break up, I have to I can't live like that, also it's my moving day today and I feel so exausted, I feel like I conceived I am 8dpo today and frustrated.. Just want to get rid of that asshole.. I am writing this now cuz I really need some support so if anyone feels supportive I would appreciate.. I am scared... I don't know what to do if I am pregnant with that shit head, cheating bastard... He is also looking at my eyes and telling me he is not cheating on me but I found out clearly that he is
