i am so sick and tired of arguing with my boyfriend i dont know what to do! We argue mainly because he thinks hes mr know it all and it gets unde my f***ing skin!! It always starts off as a debate, then an argument, my anger turns into sadness and i just start balling and eventually we get nowhere! We are moving in together this next and i honestly just dont know how its going to go! any advice?? We love eachother alot but it still makes me wonder if were really going to last
