I was with this guy for a month and everything was good. He recently broke up with me about a week or two after going off his anti depressants. I don't think he consulted a doctor or went off of them gradually. I'm not sure. We were making plans to hang out for the coming week and then he just stopped calling me and wouldn't return my calls. He ordered bedroom accessories the week before he broke up with me. The last night I spent with him he was a little goofy, but nothing unusual. Then the next week, my friends said his mood/temperament had done a complete 180. I saw him a week after we broke up and he was talking to himself (we were on a basketball team together) and was very aggression/into the game. Not creepy, just beside himself. What happened? Did he use me or did this have to do with withdrawl from his meds?
