Fixing Trust..

I'm sure there's several women out there with the same problem I have... Somewhere down the line, your SO has lied to you about something, whether it was little or big. My question is... How long did it take you to gain full trust for them again? How do you tell yourself not to think about it, and how do you not let it create further arguments? This only happened over the weekend. I was mad for 24 hours. We apologized and got over it. I was happy all day yesterday. Now, today, I'm starting to think about it again and I struggle to let these things go because I am always wondering what else they could be lying about. I don't want to get to the point of questioning where he is and who he's talking to 34/7, or looking through his phone, or stalking his social media. Help?
