HELP!

My Boyfriend And I Broke Up A Month Ago Over Something's That He Wasn't Doing Right, And Those Things Are Communicating, Always Putting His Friends Before Me, And Just Taking Me For Granted. But We Could Never Just Talk Things Out Because It Would Lead To Him Being Disrespectful And Yelling Over Me. So We Actually Took The Time Out And Met Up With Each Other And Talked Things Out Without Yelling Over Each Other. And He Began To Tell Me How He's Willing To Change And Make Things Right With Me, So Of Course I Took Him Back 😬. And Now Weeks Later He's Doing The Same Things He Said He Wasn't Going To Do Anymore! So What Do I Do? Do I Keep Fussing About It, Do I Break Up With Him Again, Do We Have To Sit Down And Have Another Talk Because He's Very One Sided And He Has A Very Hard Time Taking Responsibility For His Own Actions! So At This Point I Don't Know What To Do And I Really Need Some Really Good Strong Advice 😪 Before I Do End My Relationship Again. He's A Sophomore In College And I'm A Senior In High School, And He Plays Football So He Has A lot On His Schedule Until The 28th Of This Month But He Also Has Breaks In Between So I Just Think He Should At Least Take The Time Out And Communicate With Me And Let Me What He's Doing & How His Day Was!
