$5 NL 99, how would you play this?

[Mase31683]

Don't have poker tracker numbers, but villain's been very active lately. Splashing in quite a few pots and going to showdown with some less than stellar holdings. When he min checkraised me on the flop I thought he might have the jack, but his turn bet just didn't seem like top pair protecting against the flush draw that just showed, which is what made me curious. I didn't want to raise the turn because I didn't feel strong enough to withstand a 3bet, so I figured call and see what he does on the river. When he made that last bet, I really didn't think I could move him off any Jack so I just called again. Besides that I wasn't folding once we got to the river, lol. What would you have done different? Or is this okay?
