When someone expresses a sentence -in most languages- the meaning of the phrase will always depend on the intentions of the transmitter and how the receiver perceives it or understands it.
It also depends on many subtle details that one may have to take into consideration such as the tone, the expression of the face, and some other non-verbal expressions, and naturally if both persons do share the same values. (See What is the meaning of the word “fugazy”?)
6 In conclusion
"Te quiero", as most people know, means literally “I want you”, but it could be meant as the opposite if it is said in an ironic or sarcastic way, in which case the answer would be -yo tampoco- me neither.
"Mucho”, well it wouldn't be necessary to translate it, obviously, everything you need to do to understand it is to remove the last letter.
