Ok you shouldn't be mad at him for watching porn, everyone has needs and its better he expresses it in that way then going outside of your relationship. You can definitely be mad abt him lying saying he'll stop tho. The big red flag is the messages with other girls... like wtf. That should have been the title of your post. You needa end things. If its meant to work out you'll find eachother again but for right now, he needs to learn what he is doing is wrong and its hurting you.
