Yeah, besides whether May is interested in Ash or not... I dun think Ash really 'loves' May... here's why..
SPOILERZZZZ (ReAd aT yOuR oWn RiSk!)
In Jirachi: Wish Maker, Ash is talking to Max.. Max was talking about not wanting to leave Jirachi, because they were such good friends, then Ash starts talking about a friend that he never wanted to leave, and did, but he said there was still a part of her left in his heart. He talked about how much he cared about her... and of course the only thing Max paid attention to was the heart thing.. so Ash... lurvvsszz Misty..
But that was off topic... sorry...
