Hamlet: Act V response

So did Hamlet really love Ophelia? I can't decide and am a little bit confused. I know that he professes his love to her postmortem, but prior to that he pretty much called her a whore (not really a nice thing to say to your girlfriend). To me it seems like he can't decide whether or not her likes her and, like with killing his uncle, he's just really indecisive about it. Obviously Ophelia liked him enough to lose her mind when this was coupled with her father's death, but Hamlet I'm not so sure about. It just seems a little to easy for him to profess his love, considering all of the nasty things he said about her.
