Homophobic abusive environment help save 4 Van

Ever since my girlfriend came out to her family we’ve been on one hell of a roller coaster. We managed to keep the relationship secret for many months, however for 6 months now, my girlfriend and I have had to put up with her homophobic mother and grandparents in order to have a roof over our head. It started off with separating us whilst we were out in public, her mother use to tell us she was embarrassed and was worried other parents would judge her. They than started to neglect us and refused to put any money towards her own daughter and I for food. She would take her other two children out for dinner or bring them home food, sometimes even cook for them but refused to acknowledge our BASIC NEEDS. My girlfriend has lost over 20kgs just in the past 2-3mnths from being neglected, we are both now very malnourished and emotionally effected at the same time I am still trying to complete my university degree and Shari is trying to become a landscaper. Moving on, her grandparents would take the other siblings out to do fun family activities, and instead of asking us to join would rub it in our faces. We have been kicked out multiple times for asking for food, money etc. We strongly believe my girlfriends mother is a narcissist and we are trapped in her web of lies. The violence has risen to the point where her grandma saw me comforting my girlfriend, didn’t agree with it, so she walked over, grabbed every last bit of my hair and pulled me off the ground, my girlfriend pushed her grandma off me just to have her grandma start choking her. No one stopped her... I had to rip my girlfriends own grandmothers hands off of her throat whilst her mother and grandpa just stood there. We are now left at a stand still as I am not welcomed back into her family for the fact I am “brainwashing my girlfriend into making her believe she’s gay”. During this period of being mistreated we got a puppy to emotionally support us, however now we have made it harder for ourselves to get a house, therefor we hope to soon buy a simple second hand van that is capable of housing my girlfriend, our puppy, and I until we can afford a stable, pet-friendly house. I love my girlfriend to bits, we can’t wait to start our own family, please help us get on the right track so we can move on and build a respectful and loving family of our own. Thank you for taking the time to read this and for all the support
