single word noun for somebody who is unfaithful to their spouse / relationship-partner [duplicate]
There seems to be a range of adjectives to describe such people, and the noun for such an action is infidelity, but I couldn't find a noun that can be commonly used to describe the unfaithful person.
he/she has been cheating on his/her spouse/partner, he/she is a __________
(This train of thought was prompted by somebody's garbled answer here that was giving an example involving infidelity.)
Please note: 'adulterer/ adulteress' is an obvious option, but its legal definition presupposes marriage, at least here in India, so I should like to find some other word to fit this question.
Solution 1:
To my mind the most descriptive idiom is two-timer, the noun form of two-time
- to be unfaithful to (a lover or spouse)
- to double-cross.
Solution 2:

Philander [fi-lan-der] verb (used without object)
- (of a man) to make love with a woman one cannot or will not marry; carry on flirtations.
or
Debauchee [deb-aw-chee, -shee]/ noun
- a person addicted to excessive indulgence in sensual pleasures; one given to debauchery.
or
Reprobate [rep-ruh-beyt]/ noun
- a depraved, unprincipled, or wicked person:
Some of these terms seem to be more gender specific, but I believe that the intended application would be understood regardless of gender. Though it is anachronistic, the essence of the description could be applied to any person acting as such.
