help!!

My boyfriend and I haven’t talked since July 26th. Words were exchanged on July 25th and he won’t speak to me since then. I’ve apologized, told him I’ll make it up, I pretty much have been begging him since then. Thursday was our 6 years and I texted him happy 6 years (he doesn’t care about these things) so he didn’t even respond. I haven’t texted him since then. His gma asked him if he was done with me, he looked at her and walked away and she felt insulted. I’ve even asked him are we done, if so let Me know so I can move on because hes gone without talking to me for 3 weeks. But this is the longest I think. I said He used me but that was only because that’s how I felt but I know I shouldn’t have said that and he always fought with me about money and ppl have mentioned me I am buying his love so that kinda just stuck in my head but I’ve been apologizing for stuff. I haven’t texted him since Thursday but I’m going crazy. He told his gma couple of weeks ago that he will never say that he’s done.

What do You guys think?
