Should I stay or should I go?
I want some advice :( I'm 21 and my girlfriend is 19. Back in 2012 we started dating and went on for a year and a half. In that time we were on and off due to her talking to boys in a "more than friends" way and 2 of the times were were "off-again" she slept with 2 different guys. We finally broke up and stopped talking for about 10 month. We randomly started talking again and got back in a relationship, which has been going preeeettttyyyy strong for the past year. She has told me how she's changed and how the "old her" is long gone. Welp, in the past week a bunch of stuff has been going wrong. First off, I've seen her internet search history and she was looking up Facebook pictures of one of her old flings. Secondly, I read her diary (I know it's bad) and she was talking about how she thinks a few of her coworkers are cute and she put winkie faces and stuff. And lastly! A old guy friend that reallllyyy liked her msged her on Facebook and she asked for his number, then she deleted the messages. I know it sounds like I have a trust problem because I do, I've gone up to my girlfriend a few times and told her these problems and she's said "Your the only one I have a crush on, either you trust me or you don't". Now, I love this girl more than anything but I'm wondering if I'd be better off without her. She didn't have the best upbringing and her dad wasn't around at all, and she's spilled her heart out multiple times and I know Im a positive influence in her life. I don't know what I should do, help please?
