i think the reason i didnt was because they assumed their underpair or whatever couldnt beat my pair/2 pair.
Should i have slow played more here or bet the pot or what? i think in most cases i am not getting called here as most people call raises with low pairs but i thought anyone with a single pair here might call.

Standard and well played. If they dont have anything they fold. I bet here as well. If they do have something they will call/raise and then you know you get them unless a scary card hits on turn/river (if you let them so far without going AI).

This stuff happens all the time, you hit top set, bet on the flop and they fold, get nut straight and they fold. better get used to it

Normally, they have to have something to pay you.

Your bet here is good. You might catch an overzealous set/two pair that will pay off your straight. Heck, you might even get a straight chaser to come along for the ride. Definitely bet here.
