Should I break up with him?

Okay so 1st of all we've been together for a while.. (about 6 months)
& he just gets to be a worse and worse boyfriend...
I just don't know what to do anymore,
*He is CONSTANTLY putting me down,
*He NEVER makes time for me,
*He is ALWAYS at his friends houses
*He goes over to girls houses and tells me if i don't like it then to break up with him & whenever i say "ok it's over" he's like "I'm so sorry baby" so we get back together
*He cusses me out

& he's just not the same guy that i knew before.. I love him with all of my heart and he knows it, but I'm starting to question if I'm just wasting my time...

Please help me and give me some suggestions

Thanks so much
