Your boyfriend has proven two things to you. That he is willing to lie about something because he knows it is wrong, and that he is willing to keep doing something even though he knows it will bother you. These are two of the more difficult things to change in a relationship. He hasn’t understood (or cared) that this is a problem for you. This isn’t worth you putting up with. If he doesn’t understand that this is hurtful then let him know that you think more of yourself than letting him be careless with your feelings by disregarding them. Inform him you’d rather not hang around waiting to get hurt again — and mean it. Be sure this isn’t a ploy to get him back. Once you say you are going, it is time to go.
Wishing you patience and peace,
