It's important to note that, even within the Tagalog language, expressions of love can vary greatly based on the specific region and social context. In a more informal setting, you might hear phrases like "Gustong-gusto kita" (I really like you) or "Sobra kitang mahal" (I love you so much).
If you're looking for a truly unique Batangas expression, you might have to ask a native speaker! They might have a more specific way of saying it that isn't commonly found in dictionaries.
