How should I say ‘Me, too’ to my Japanese girlfriend in Japanese?
It depends on your cases. If you would like to say ‘I feel the same!’ , you should simply say
You may say 「わたしも！(Watashi-mo!)」. However, it is a bit weird for you to use ‘わたし（Watashi) to your girlfriend because you are a male gender and you don’t need to be formal to her.
You better to say 「ぼく(Boku), おれ(Ore)」 to your girlfriend. These are the casual Japanese for a male gender. Your Japanese girlfriend feels closer to you.
