Should I leave? Just found out....

Just found out that my husband looked at celebrity porn apparently...and right before that, he googled two names of girls I know that I believe he used to be attracted to.... I messaged him telling him that he's going to lose me mentally, physically, and emotionally for awhile if not forever....we're still 11 months into our marriage and things have been weird since we got married! What should I do?

Clarification- we've both discussed our feeling s against porn and he said that the last time he's ever looked at it was around 15 yrs ago. (Not so...)- even if that's not worrying, the two girls are worrying me...
