Villain is running 25/15 and seems OK. I have been playing relatively LAGish.

Villain raises to 14 UTG, I reraise to 30 OTB with , villain calls.
He started with 390, and I cover.

Flop (60)
Villain bets 45, I call

Turn (150)
He checks, I check behind

River[7d] (150)
Villain bets 125, Hero???

Edit. it was a Q not a J

I don't like how you got here, but how this could be anything besides an easy push is beyond me.

I was actually villain in this hand with and figured him for a PP like KK or QQ, (or maybe a weak ace ) and tried to move him off it. It failed and maybe was a bad spot since I didn't really rep a hand, I guess.

i would sometimes bet turn, fold to CR.

i would also sometimes check turn behind.

i would never expect a weak A to fold. and i wouldnt even expect villain to have a weak A here. from a competent player i think AK, AJ, AT take this line and never fold the river.
