My GF doesn’t have a job after 8 months and now on disability benefits

My GF who I’ve been with over a year had lost her job because she was letting people steal food because she felt bad for them. Eventually her boss found out and sacked her with immediate effect, also threatening to get the police involved.

Some background information, my GF does have severe autism so sometimes she doesn’t know she is doing wrong and thinks helping people is most important and often forgets company policies etc.

For the past 8 months after losing her job which she held for a year and was job hopping previously she was able to get 2 interviews both of which she never got the job and the rest had never even responded to her resume.

She then gave up and broke down to me saying she’ll never be able to find work because of what she had done and lack of qualifications etc. Soon after she had gotten in touch with her parents to sign up for disability benefits to which she was granted due to her autism, now she doesn’t have to work as she gets paid just enough to stay afloat and no more. So the house we live in she’s able to pay all the bills for and such along with groceries.

The issue is she wants more, like if we need a new phone, drive to places, eating out, and such. All these leisure activities come out of my pocket whereas before we could easily split the costs between us. This has taken an effect on me financially as before I’d maybe spend 400 to 500 a month, now spending sometimes up to 1600 to 1700 when my wage is only 1800 a month.

TL;DR – GF with autism lost her job and now gets government disability payments may never be able to work again. Doesn’t get paid as much as she used to so now is straining me financially. Looking for next steps.
