This hand may make me look stupid

but i have been reading a book about bluffing and naturally, i have decided to 'speculate' a lot more in my recent games. Take a look at this, is this my fault?

Was this a bluff that was just never gonna work?
There was no preflop raise so i didn't expect to run into a hand as big as this but would you have called with just top pair?
Also, generally in this situation when he calls my reraise, is this a signal to put chips in, back off or does it just depend on the situation?
Thanks
