found hubby lying.

Sorry this is long 
  
 my husband knows im not dumb and im very tech savy. So i got on thr tablet today and looked at his history snd of course found porn and even a dating site.. so i confronted him and asked why he was wstching porn and why the hell he had a dating site. He said the porn he only watched while i was healing durng my 6weeks pp (which wr had sex during a couple times anyways? Im now 15 weeks pp) and that the site was an old site from before we were together and they had sent him a reminder email like a "we miss u come back" so i then looked at his email and found an email to reset his password, so i told him if that was the case then u wouldnt have tried to reset ur password? And he said it still didnt even work and he was just curius cuz it was an old site he used to use. I call bull shit. He told me he loves me and that he honestly wasnt using it like im thinking and he finally admitted to the porn, and then as im on the tablet all the google stuff logged out and he reset his password at work (weve been texting all this) why reset your passwords so i cant look anymore if theres nothing more to hide? Im reallyhurt by this and dont want to be nieve and fall for some dumb lie. I also dont want to over react cuz before we got married i cheated on him.. cold feet i guess idk. But he forgave me and weve been great its been 4 years, and idk... hes never lied to me before about anything and maybe it is all how he says, but i just feel like theres more to it. Has anyone gone through this and what was the out come?
