Making Myself Crazy.

First and foremost, me and my SO have an open phone policy. But that doesnt mean I get to just go through his shit whenever I feel like it. But last night he went to shower, and he left his phone to charge right next to me. well it vibrated. And I looked over at it. which I always do if it's by me and hes doing something else, incase its important and I need to get him. But it was a snapchat notification, from a name of a female I have no clue who she is. and maybe that's not weird for some people, but me and my significant other have been together for a long time. We have kids. I know all of his friends, and his family. So this name im like, who is thatt. and I wanted to ask him but I didn't want it to seem like I was looking through his phone because I really wasn't. I tried to search for her on other social media and he doesn't follow anybody with that name. And it's been driving me crazy. I should just ask him. ugh
