Answer:
I am so sorry this has happend to you! I would definitely talk to both your mom and gf about this issue. I would tell your gf how you feel. If she seems not to care then it is most likly not a great relationship and will end up being toxic on your end. If it is toxic on your end it is going to make you unhappy which could lead to depression. Like I said I would just talk to her and see how both you and her feel. I wish you the best of luck
