Number one NO NO!!!

cant think of anything to write...my head is clouded by useless thoughts...maybe it has something to do with the text i receive this morning, an ex of mine send me something that some how made me feel bitter and angry at the same time, we are not actually a couple because he never really want to commit himself to me so we have that mutual understanding stuff. my only mistake is that i let my self fall for that person which is the number one no no in an open relationship...
