What does it mean when he doesn't text back?

So me and my ex broke up a month ago and the day he broke up with me and said he would stay in contact with me and come see me once in a while, and video chat with me. Do I said you promise and he said I promise. So a couple of weeks pass I texted how he was doing, it took him a few days to replyand he said he has been busy when he clearly wasn't by the pictures on facebook when he was at a party. Then a week went by and I asked if he would want to get together, and he still hasn't replied back it's been a month now, and no reply and it said he has read the text message on my iPhone. So what does this mean. Someone tell me and please be nice about it. Does he want to be friends or no.
