Freedom Stay in School and not lose her Residence

Hello loves so I'm about to get personal. I'm, not one to ask for help usually I like to find any way I can to be self-sufficient but I have been placed in a situation I could not have expected to be put in..

I am a student at Brigham young university and got in a year after living here with Jonas my ex-spouse. This is a dream for me because I never thought I could pay for school or get good enough grades to get into a university! Life threw so many curveballs making schooling near impossible, becoming homeless right out of high school that I had lost previous scholarships. Now, at 26 I'm thankful to have made it to BYUH after hard work preparing and applying!

when Jonas left He still promised to pay his side of the rent because that was the fair thing to do and kept up his side of the bargain. I have been paying my part of the tuition and being as cordial to him as I could- I went through all the belongings he left behind, sorted, organized, and carefully packaged them so he could have all his things. I was left to take care of everything and made sure to pay him any remaining dues to be even and fair and respectful Hoping in his words to "invest in a future friendship" After doing all of these things I get an abrupt email saying he's decided he refuses to pay his end of rent completely out of nowhere. Now it is past the due date to pay for rent and I am not going to be able to start the new semester if I cannot pay 4000$ before January 4th! This has been the hardest semester of my life and I have done the most heartbreaking thing to choose myself, my happiness, and my personal growth in education. I need your help please friends and family! I am in need and am doing everything I can in my power! Your contribution would mean the world to me!!!
