I need help with a decision?

I have been with a guy for a yr now (talking)but we are definatly going out together. he has said he loves me and calls me sweetie when hes drunk, but he keeps disresecting me I think. he leaves me waiting to here from him for hours, or doesn`t even call.I also know he is still visiting the personals and trying to meet girls(is that cheating)I wait and don`t make plans because he said he would call. help i`m so heart broken, i thought he was a stand up guy
