I guess i got Karma?

It is 1 year and a half since my fiancée decided the for some reason he couldn’t trust me and ended our relationship. I miss him deeply and it hurts my heart when i miss him. I not only lost my love of my life, but my best friend. I really want to sit down with him and talk things through, but since i dint have his number and he deleted all his social media accounts, i cant fully move on and heal from the break up. Ive stopped eating and gone into full depression, thinking i am the one who caused all of this and that if i did do something wrong, then i cant be loved because I'lljust keep messing up and not know what i did wrong in the first place. After he endedour relationship, my life just went down hill. Im loosing my house, my family moved away, ive lost my only other friend and im struggling financially to even make basic needs.
