My first (and only) boyfriend, with whom I was with for seven months, became more and more possessive and controlling as our relationship went on. He began getting angry when I would be busy with school work or was having a girl's night with some friends, and would demand to spend more and more time with me. He began to grab and pull me around, and I ended up breaking it off when he picked a fight with me via text message for not answer his texts immediately (I was in Glass-Blowing studio for 8 hours, and was not able to have my phone on me due to the high temperatures I was working with (2000F+).
He had started getting more and more controlling, and would tell me to deal with it when he had upset me..

Has anyone else had experience with possessive boyfriends or girlfriends?
