A sincere apology, love. This is really not the time to get into an even bigger argument about how his actions made you act a fool. Sure people can influence our emotions but they can’t make you do anything. It’s time for you to put your big girl panties on and take responsibility for your lack of judgment. Whether you’ve decided to terminate your relationship, or are going to try and work it out, you need to let him know that you’re not crazy enough to believe that your actions were acceptable.
