My partner of two years gets a lot of Snapchat’s on her phone, always has. 

She says there just from friends that she’s had longer than me, but for some reason I don’t believe her. I think that she’s flirting with these people online. 

She caught me trying to look at her phone, but she won’t let me look at and was very defensive and called me controlling. She’s not displayed any behaviors that would make me think that she’s cheating. 

I know that many people who are bipolar, sabotage, relationships. I’ve got no way to prove that she’s cheating and if she you can hide a lot online.  She feels like this conflict  came out of nowhere.
