Thing s i gave him chances befor. He usd to lay hand on me he woul pick me up and drop me on the floor. but that has begun to stop, now it seems its just pushing and slapping. Now i do pertake on tese fight because i yell at him alot in public and other places and i try to contain myself and just ignore his pestering ways. His latest things are calling me names like *****, ******** ext. I do call him names also. I just really love him and i feell like everyday the we fight i begin to fall out of love with him. Any advice??
