They apologized, but I’m still really mad

Your feelings are really hurt.  They apologized, but you’re still angry.  Was the apology all it should’ve been?  There are 5 critical elements of a “healing apology” that ease the hurt and repair the relationship.  One, the offender must acknowledge the reasons for your pain and own their actions.  Two, they must accept blame instead of putting it on you with that, “Gee, I’m sorry your feelings are hurt” stuff.  Three, they don’t take an accusatory stance.  Four, the apology isn’t conditional.  There are no strings attached.  And five, the entire apology effort doesn’t leave you feeling worse about yourself.  If you’re still angry, then there are issues that need to be addressed.  Does this person treat you poorly way too much?  Is the relationship unhealthy?  If you’re still angry, accept that it’s valid and take action.  Apologizing fully and sincerely is an art.  Teach your children well.
