Me and my girl have been going steady for about 3 years. We aren't a perfect couple we sometimes get in fights as everyone else does. We go periods without talking but we have never left or thought about leaving each other. One day we we are in a usual fight and she's talking to a friend of hers, who is also a mutual friend of mine. He begins to ask me questions about what I'm doing with other guys. I tell him the honest truth. She seems to know what i tell him later or on even though there was nothing bad. One day i see him holding her face and she smiles. They walk away and I go up and ask her what was that? She says nothing for a while walking away and tells me I'll never change. We don't speak for a while. The next two days we meet in my parking lot and she tells me she didn't mean it and she loves me. I believe her. The next day she's talking to the guy again but she says it's not in that way. She stops talking to him and begins talking to his friend, with  she makes out with. We sat on the phone and she told me I can find somebody else and that I'll be okay without her. Two days later she comes back and says she wants me back. I take her back. We've been together a year since this happened. What does this say about our relationship. Also a long while after this happened, we were in another argument and her ex texted her. They texted for 3 days and they hung out once for a car ride. She cries and begs me to stay. I am hurt by this shit. I asked her why she did this, why she was getting attention from the first guy, she says it's because I was treating her wrong. But she also says she didn't want him to stop. She even once said that he was right about me.
