Should me and my boyfriend break up?

Your not a whore, you clearly looked at things and have decided this is not going to work. but before you jump into another relationship, consider taking time in between as to not hurt anyone or set yourself up for disappointment. i would be cautious with a guy who falls for other peoples girls- he may find he has a thing for the "challenge". Plus, love does not come freely or easily, its worked at, which means something has been going on between you two emotionally for a while or he just jumped the gun. take space for yourself, enjoy the changes that are happening with school and meeting some new people. be careful with whom you give a chance to. and end that relationship your in gently- it sounds like its time.
