pwettybird you are so young and this is probably not what you want to hear, but... It sounds like you guys are in a cycle of self-destruction. Couples counseling would help because it sounds like you two don't know how to argue or compromise without it escalating into the end of the relationship, if you can agree to go together. But the silly things (like ringtones and wallpaper) you're fighting about are probably not really what you're fighting about. He gets mad and threatens to leave knowing you'll cry and beg him to stay. And you end up blaming yourself and saying that YOU want to change. Why should you be the only one who wants to change? Shouldn't you grow together as a couple? If your story is correct and you were just moving the cord around, why should he get mad about that?? Maybe it's time to take a step back, take a deep breath, take a break from each other. When it's the little things that are causing an eruption, there's definitely something more sinister lurking below. Did you guys jump in too soon? I think you might have a little soul-searching to do.
