Anxiety and relationship breakdown during covid

I am reaching out as I am struggling really bad with anxiety and depression. I am currently in Victoria in lockdown and the past year I have been in a long distance relationship with a guy I believe is my soul mate. Being in long distance has been hard as I miss him all the time and I found myself causing little arguments for no reason due to frustration. Then covid broke out. My partner and I planned for me to move to his state- I landed a great job and we planned and told everyone. The day I was going to sign the contract for my new job, my partner changed his mind and didn't want me to move, then wanted a break to then broken up. We have stayed in contact and he tells me he loves me and thinks I'm his soulmate too but just thinks we need time apart. I am extremely heart broken and I am falling into a bad state. I cannot let go of him and begin to think to move on. I am so broken and I don't know what to do. My sleep, my health, my mind and heart are messed up. I don't know if I should hold on or what to do. He seems fine living life happy and I'm stuck in melbourne. I'm so confused and lost

any advice would be amazing
