I paid for my girlfriends fertility treatment, can I write this off as my medical expenses? I am married but separated. She is working in the US under a green card.

My girlfriends name is listed on the documents as the Patient and Responsible Party for the billings but I paid for everything.

Only if you claim her as a dependent can you deduct her medical bills.
