Picture this scenario. Your partner surprises you after work with a bouquet of flowers and he tells you he's made reservations at your favorite restaurant. The gesture couldn't be nicer, but when you inform him that you have a prior commitment with your best friend he becomes angry and insulting.
Seconds later, he swears he was only joking and he says he loves you more than life itself. These reactions are not your fault, nor are they normal components of a healthy relationship. They're indications you're entering dangerous territory in your relationship and you need to evaluate whether to continue seeing him [source: Center for Relationship Abuse Awareness; In His Steps].
