I'm sucking a big one!

Since Sunday my game has been awful. Personally I blame the Cowboys! Seriously I know part of it is the variance but part of it is reverting the old style of play and being a little tentative towards the end....last night for example I am playing in a 10.00 buy in 45 man SNG. Pays 6 spots. When we get down to two tables I am on the table with a jackass...jackass from some country I have never heard of was being extremely aggressive. He is the chip leader but everyone is playing tight and he is stealing tons of hands. He is in the BB and I am the button. I hit KA suited. I raise the blind 3 X, SB folds, he calls my raise. Flop comes and I hit nothing. It's a 2-10-5 rainbow...He checks so I check, Turn brings an 8, same thing he checks I check. River comes and it's a 4. He raises to 2K, so I think whats this asshole doing? Does he had a pair and slow played me? I don't think so cause he just loves to raise every hand but maybe....did he hit a 4? Maybe that is my biggest worry or that maybe he had pocket 4's and he hit a set....I had hold em manager running and he VIP 70%!!! So I think naw dude screw you your bullshitting me and I think my A-K is best, and I am suspicious about the check's then the stab. Usually if your checked to the river and you have A -10 and up with only two players usually you have the best hand....so I call and wham I win...He had a 3 - 7 off suite! I send the message "nice try" and he tries to say I am a bad player because I called. I pointed out that #1 he called my 3X with 3-7 off suite and that that his VIP is 70% which makes him a horrible player and he sucked. After that the table stop buying his bullshit and he was gone at #9. I love busting idiots...but then am I the idiot? So we are at the bubble and I am average stack with about 20 BB's. There are 2 players with monster stacks. One is very good and one is so so. I get lucky. I am pushing when I can at the smaller stacks taking advantage of there weakness around the bubble. I hit AJ suited and the person in second who has about 2 1/2 times my stack size calls...she has AQ Suited. Crap! Like these things happen I caught a J on the flop and double up. Hooray! I am now in second. After 30 minutes the bubble finally burst. I am third now....the top spot pays around 170 something? second pays low 100's, third pays around 75....sixth pays 27.00 so basically a 17 profit...I have been playing for two hours and I don't want to win 27 I want big money...not because of the money I want to get up and dominate and win. What do I do?
I have that good player to my left a few spots away and I push with A-J suited again and he calls with AA so I am knocked out at 6th so I win 17....so now comes the second guessing....should I have just called or raised and see what he did? (probably) stacks were getting shorter so really at that point it was shove or fold...should I have folded? with the chip leader to my left the answer probably was yes. However earlier in the game I had a guy go all in who was a tight player but short stacked. I am sitting there with A-Q suited thinking when it gets to me I should push, but then another guy calls his all in and he is pretty big stacked....so I folded believing that against 2 all in's from two pretty tight players my chances of winning just dropped a bunch....of course the board would have given the A high flush but I still think I lose that more then I win it so it was correct but it still doesn't mean it doesn't mean I second guess myself. Back to last night...I think the answer should have been to fold the hand....what does everyone else think?
