not crazy wife

Well its kind of hard to explain. We have been together for 4 years married 1. Everything was picture perfect until I got pregnant with my first child. Then he got a job out of town and ran off and cheated on me came back and cheated on me. I sadly forgave him because I wanted him in our daughters life. Things went better. A year later we got married. Then its like all of a sudden I'm having trust issues badly now. and he's doing everything right. I mean sometimes he looks at dirty things on his phone and I know it's a guy thing. But I can't seem to make myself believe that. I get so mad and hurt when I see it. And now it's like I constantly find myself checking his facebook seeing what he's looking at or who he is adding, making sure therez no naked women on hia newsfeed, checking his YouTube account for dirty videos. Looking at his phone history all the time. And always locating him during the day. It didn't all start until he got a 2 week on 1 week off job. Out of state. I mean everything is prerfect I know he's not doing anything wrong but I drive myself and him crazy. I now have his google and YouTube account blocked so he can't get on it on his phone. He's kinda dumb so he doesnt know how to fix it. But I promise I'm not a crazy lady! I just really want to stop being this way. I can't even watch a movie with a pretty girl In it in front of him or a sex scene without getting mad. Or see him looking at a pretty girl when we go out. It hurts so much. But I trust him and love him now more then ever. But idk what to do with myself I need help
