Did I play this right?

I really dislike the flop 3-bet. There doesn't seem to be a reason to jam this flop unless there's more of a crowd involved. Getting UTG+2 out isn't important since your J and T's are almost never outs here and you won't be able to clean it up or boost the pot size enough with the 3-bet and that doesn't even consider the potential of a cap which did occur. You still will have odds to call for your open ender even if the diamond doesn't come albeit a smaller overlay but you'll end up putting less in on the flop where you are simply paying off the real hand with this action.

If the diamond does come you only need about 1 in 3 to call the turn and that's pretty much a no brainer.
