Hello- Thank you for asking the question. I have over 30 years of experience working with individuals, couples and families & am happy to reply.
I am sorry to hear about this. It sound like your girlfriends mother has a unresolved depression which has resulted in her become more anxious, afraid of being alone, and dependent. This is not uncommon and can be treated however, her mother needs to see a mental health professional for conclusive evaluation and treatment.
In the meantime, I suggest reading the following information from Harvard University that will help you understand and to help the family.
If you have additional questions, feel free to ask- I am happy to help.
Kindest regards, Bill
