I was in a similar boat. 1) He needs to understand why porn hurts y’all’s relationship 2) He needs to stop watching it for himself and not as a incentive not to lose you. Pornography can be addictive and like all addictions it only pushes those that actually love you away from you. 3)Do not allow anyone to tell you that you are insecure. You are not insecure You’re just not a cheap egirl. You require a higher, respectable standard from the man that you are sharing a bed with 4) remember that your boyfriend is human and humans will make mistakes. But as long as he is not being manipulative and a jerk about your concerns for your relationship I would process his mistake and move on
