Why all this discussion about changing solvents? There is only one viable solution - she has to go. Buh-bye. Had a nice time, might have worked out, blah blah, buh-bye.
This is you saying, "but you're my soulmate! I LOVE YOU! I want to have your babies!", and this is me saying, "BUH-BYE".
As someone else mentioned, there's petroleum in much more than just gun cleaning solvents. I have lots of allergies, including a pretty serious one to chlorine that closes my airway. Allergy medicine is your friend for the tamer stuff and if you're really concerned, get an epi-pen as a "just in case" for the stronger reaction.
