Q:

Can a Paladin's Cleansing Touch (inadvertently) Dispel Simulacrum?

In our last D&D session, I was playing as a simulacrum of my PC that was sent by the BBEG after my PC had been captured. About halfway through the session, the party noticed I was reluctant to use my spells and was more afraid of damage than normal. The Paladin suspected I might be under the influence of some spell, so he offered to use Cleansing Touch. I figured the simulacrum would assume this functioned like greater restoration, so he willingly accepted the offer.
The DM and I weren't sure what should happen in this situation. My first inclination was nothing would happen because the simulacrum itself is a creature with no spells affecting it. However, it also seems valid that the spell Simulacrum is animating-"affecting"-the simulacrum (creature).
What are your interpretations?
Edit:
I did some additional research on the question and I think I found some more information that might be useful.
There are some great responses on Reddit to address the "multiple spells problem" mentioned by @Someone_Evil. So I believe that part of the question can be addressed by the DM asking for more the Paladin to be a bit more specific on what he is trying to remove. I'll update this more as I do more research.

A:

You're probably fine
Firstly, let's establish whether simulacrum can be dispelled. (I'm going to be assuming the simulacrum is targeted and says itself willing - as is/was your case - because otherwise it would plainly not happen and/or be a different question.)

It has a duration of "Until Dispelled" which means it is a spell to be ended (and not just the effects of a spell with a duration of "Instantaneous").
It's probably fair to say that a simulacrum is affected by a spell: simulacrum where affecting means "causing it to be a creature rather than a pile of snow".1 The exacts of what "affected by a spell" or a spell being "on" a creature is not well defined in the rules.2

Paladin's Cleansing Touch looks for a spell on a creature:

[Y]ou can use your action to end one spell on yourself or on one willing creature
  that you touch. 
--- Player's Handbook, p. 85

Which presumably means "one spell affecting that creature". So there is a reasonable argument for simulacrum being endable by Cleansing Touch.
The (remaining) problematic bit is the "one spell" part. What it does mean is that it doesn't end all spells on the creature (as dispel magic does). But it doesn't say how that spell is chosen. Is it one spell of the Paladins choice? One of the DM's choice? One at random? Personally I would rule that it is one spell the Paladin knows about and chooses, meaning  unless the Paladin wanted to (sort of) kill you for that session they wouldn't end the simulacrum on you. Unfortunately this ruling also makes the Cleansing Touch feature not do what the Paladin is trying to do to you (i.e. remove whatever unknown spell is affecting you). If your DM is crueler than me (don't let my username deceive) - but it doesn't sound like they are - they might rule otherwise. 

1: The alternate ruling is that only the original, in this case your (original) character that someone has stolen captured, and that the simulacrum is only an illusion-but-actual-creature that isn't being affect by, but is instead the effect of the spell. This would mean the spell can't be dispelled by Cleansing Touch at all (via the simulacrum).
