We can use 'like + to infinitive' or 'like + -ing', both have very similar meanings.
However, in the second part of each sentence, we need to use the verb "want" because we are talking about a specific desire in that moment ("now").
We use the structure 'want + to infinitive':
I like dancing, but I don't want to (dance) now
I like to dance, but I don't want to (dance) now
If we omit the second dance (in brackets) it sounds much more natural:
I like dancing, but I don't want to now
I like to dance, but I don't want to now
