We've been dating for 2 years. I'm 28 and she's 27. It seems like a very immature situation I know. In a way I want a reason to stay because I've already invested time in her and I'm not getting any younger but at the same time I don't want to open myself up to being lied to again and again every time she feels like she wants to open a Snapchat or talk on there. In my opinion there is no reason why a guy should be sending any snaps to another girl that's in a relationship when they have each other on fb. Sc is just too private and sketchy but that's my opinion...
