I don't think your raise is that bad because it is going to give you a lot of info, particularly if this guy pays any attention to your table image.

You have given yourself a chance to get away from the hand if you really want to and also a chance to see where you stand.

To me the min raise is either real strength or real weakness. His re-raise is showing real strength. In all likelihood you are behind here and now it is a question as to whether you want to gamble.

Had he just called I would have pushed on the flop.

I wouldn't take the long pause as weakness either, I quite often find this is a show of strength when they are making this kind of move.
