I Am Mad, Sad, Disappointed

Ay I don't even know where to begin in this story I'm so disappointed and disgusted and frustrated and angry and sad. So along time ago about 2 years I dated this one guy who wasn't the best but we were together about last year we separated and never spoke again until recently he owed me some money so I contacted him any ways I really liked him but moved on in my life and I thought he was a decent guy that he wasnt low like the others only today I found out he did something that really upset me and now I have to stress and undo it ay who can we trust in this world anymore I mean a person u think is a partner a friend a lover is out to hurt u and ruin ur life but I'm so disappointed in him because I never thought he would stoop so low and do that ay my god pls take me away I'm so tired of this world.
