Is this a heading broccoli, broccoli raab, sprouting broccoli, or Chinese broccoli? What country/location are you in?
Sometimes too much nitrogen will promote leave growth at the expense of flowering/floret formation. Broccoli, a cool-season crop, also usually requires a period of cold to encourage bud formation; some cultivars are more heat tolerant.
On average, broccoli will mature between 60 and 120 days, depending on cultivar and conditions. It sounds like yours has gone beyond that point. However, if you are growing sprouting broccoli, some of those varieties may take as much as 220 days to mature. In this case, wait a little longer.
If you are growing regular heading broccoli, you might harvest the tender leaves and start over again, but first, just to be sure, you might ask someone from a local nursery what is normal for your area. If you live in the United States, you can also check your county's Cooperative Extension service:
