He is my heart but he makes me cry?

I am madly in love with my bf. We been together for a year now, but we are not doing well. 2 months ago I happened to cheat on him and I told him...It took him awhile to move on...and we were happy. But recently he has been telling me to **** off and **** you asking me If i want to be with him...I do but it seems like he doesnt believe me...He doest trust me...And i tell him the truth all the time but he still yells at me...I cry when this happens cause it breaks my heart...Then when I say that i am leaving you...he curses more at me and lets me go...day later he calls back and says he cant live without me...I just dont know what to do anymore cause I have been acting funny...like I dont say things to him i dont joke around with him anymore cause I know that he will get mad!! He says I treat him like ****...wen i put him b4 anyone in this world...Can you give me advice to say to him tonight to make him realize that I love him,,,or sould I just let him go?
