Me and my girl have been dating for awhile and we've been very open about everything. She knows my passwords to my social media and I know hers. We don't ever get on each other's but we still know them. So a couple months ago she told me about a 2nd Snapchat. (I already don't like Snapchat bc I think it's a very easy way to cheat) so when asked for me to see it she told me no. She wouldn't give me the password. This was a Snapchat used for "sexting" basically before we got together. I have asked a couple times for it and she always tells me no. She said she has deleted everyone off of it except her cousins and that's it. I know she still gets on it. by the way she wouldn't even tell me the username until I found out myself. When asked she always tells me. "Its mine" "I'm not telling you the password" "do you not trust me" what do I do? Please help me. It's eating me alive to know what's on it.
