Is this okay or am i over thinking?

Me and my ex have been working toward getting back together we have some trust issues between us he cheated and so did i but he also told little lies from time to time but we are trying to move past that..but the problem i have is he licks his phone and laptop and also hes on a dating website he told me he was gong to delete it he hasnt i asked why hadnt he deleted it he says he doesnt remember saying that and he didnt delete it b/c i might leave him...the website shows the last time he was on it its be 30 days but it still bothers me even though we dont have an official tittle..do i have a right to be mad???
