What's a word for someone who "gave up on love"?
Jaded is used to refer to that:
lacking interest or desire because of experiencing too much of something.
Or the less formal common usage as per the Urban Dictionary: The end result of having a steady flow of negative experiences, disappointment, and unfulfillment fed into a person where they get to the point where their anger circuits just sort of burn out and they accept disillusionment.
In children this condition might be called "attachment disorder."
For adults, the phrase I've heard is
He had been disappointed in love
And the result is that he is
aloof
(It could be a she, also.)
- Emotionally reserved or indifferent; 2. Distant or uninvolved
(thefreedictionary.com)
OR
embittered
Make (someone) feel bitter or resentful.
given up on love? Or someone who doesn't or can't love anymore, or is perhaps too damaged to love again?
"Disillusioned romantic" is overwhelmingly the most common expression I've heard to describe a person fitting these characteristics. Certainly when my mom describes me the term comes up.
...Thanks, mom.
