what is going on ?

My need to be loved got me hurt again ....I thought I had fallen in love when really all I had done was settled for what was offered to me don't get me wrong I did think that the guy was good looking but hey maybe we should of got to know each other more before we moved in together .....I got pregnant & lost his baby ....by a miscarriage....so just 3 days after it happened he left me alone to deal with it while he went out and smoked drugs ..........meanwhile my ex finacee told me he still loved me this was the moment I had been waiting for for 2 years he said he wanted me back and wouldn't mess up again
