damaged

Yesterday I was on our computer and I happened to come accross some files on the computer that were links or something to porn videos from some sites. And the dates on them were at the end of January and February. Even a date on there the day before we got married. We haven't even been married long. I saw those files in there in recent documents along with a lot of stuff and I knew that those were to porn videos by the name of the links and it was a real audio video file I think but it wasn't on the computer anymore if it was. I guess it had already been deleted. Well in January I also found out I was pregnant. And then like 10 days later there is a date on there to a porn link and then the date before our wedding. Back in december he told me he had watched porn and all online but that he knew it wasn't a good thing to do and that he don't do it and he told me at the end of December that he was cleaning his computer off cause he didn't want any of that stuff on there. So I figured he lied to me and I took off my ring and left it there by the comptuer and I called him at work and told him I was moving my stuff out of our house. We just started moving in over the weekened and hadn't even finished movign but I still had a lot there. And I told him why and he acted like he didn't know what I was talking about. Then he came home a little later while I was moving. He didn't say anything to me for a while. Then he started helping me take my stuff out the house. Then he said I was going to an extreme and all that about leaving and stuff. And I kept telling him about that stuff and he kept acting like he didn't do anything so I got on the computer and showed him what IS saw and all and he told me that was on there becasue he was cleaning stuff off of his computer. I said it couldn't have got in recent documents unless he clicked on it. He said he clicked on stuff to see what it was and all and that he was cleaning his computer and kept finding things. He says when you visit those sites it saves things to your computer. The links on there all looked like real audio files. And I also showed him all his email in an old account he had where it was filed with porn from this site and at the botton it said he joined the site on Jan 17, 2003, and that was also after he told me he didn't do it at the end of december which he also said he didn't subscribe to nothign. And he said he didn't join on Jan 17 2003. He said he don't even use that old account anymore and that they keep sending him those emails even though he keeps trying to unsubscribe. Je said that he did join about 4 or 5 years ago though but that they keep sending him mail even when he unsubscirbes from it. He deleted that whole account yesterday. I'm just very upset cause I don't know why he lied to me at the end of december and then I find those links on there with those dates on there after he told me he didn't do it and that he was cleaning the computer up. He said he saw more stuff on there too and that he would have to reinstall everything to completely clean everything off. And then to see the date on there a day before our wedding and after I told hm I was pregnant? Why does he keep lying and insist he's telling me the truth? So to make a long story short, I left him yesterday. And I'm pregnant with our first child. I'm about 12 weeks pregnant and now. Did I do the right thing and should I never go back? I just can't deal with lies though.
