2/4 NL, am I a tilt monkey?

[AdamBragar]

I'm a big fan of raising with suited connectors from all sorts of positions. However, I'm now also starting to call some raises with suiteds and I'm putting myself into some tricky situations. Here's one of them...

Villain in this hand seems to be entering a lot of pots but not raising very frequently. Post flop he seems to overplay his hands.

Folded to villain (513) in MP who raises to 15, I (I cover) call in LP with 5 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/spade.gif[/img].

Flop: 7 [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/heart.gif[/img]
Pot: 35ish

He bets 20, I call (Is calling here ok?)

Turn: A [img]/images/graemlins/spade.gif[/img]
Pot: 75ish
He checks, I don't like this card, but I bet 50 anyway. He calls.

River: 6 [img]/images/graemlins/diamond.gif[/img]
Pot: 175ish
He checks, I check

Comments on all streets appreciated.
