Fixing cracked bumper

Hello,

First off I wanted to say I come here every once in a while and check this place out and see that everyone is very helpful on answer questions for others. I have posted a couple of threads requesting help, and I must say that everyone that answers my questions, helps me out alot.

My question this time though is, well a couple weeks ago, I parked in a parking lot, and hit that cement curb thing, and when I pulled back, it tore a side of my bumper off cause there was a rebar sticking out of it. Anyways, the side of the bumper came down, and when I saw the holes that hold the bumper in place on the side ones, the holes we just ripped, so what I did, is somehow screwed my bumper back in place. The thing is though, there is a place on the bumper, that one part stayed attached to the car, and it tore apart the other part. What I want to do is glue these together. I tried to glue them together before, but it just made a big mess, and I painted over it, and look like crap but held its place. But now it cracked again. What I want to know is, how can I patch this up, so it looks like nothing happend, or at least it doesnt look that bad. How can I do this, I dont want to take it to a body shop, for some little thing I can probably do, and not have to pay so much money. Any help would greatly be appreciated.

May the future bring you more joy then pain.

Do you have a picture of the crack?
