Broken promises occur for many reasons including over-commitment, unforeseen circumstances and even pure selfishness. If you have broken a promise to your boyfriend, but your intentions were good -- say, there was a family emergency -- then he should have no trouble understanding. However, if you have broken a promise because of bad judgment or recklessness, then you have some work to do to gain his trust back. Remember that broken promises wear away at trust, and trust is the foundation for healthy relationships.
Tell Him Early
Give your boyfriend advance notice if you have to break a promise. This will let him know that are considering him and it gives him a chance to make alternate plans if need be. Let him know why you can't follow through on your promise and try to reschedule if you are able to. Be clear and tell him as soon as you can.
If you are good at making promises, but poor at following through, the trust in your relationship is at stake. Your boyfriend may struggle to trust you to take care of important things. Before you make a promise, be sure you are promising something that you can follow through with. If you mistakingly promise to do something you are unable to do, apologize right away and help find a solution to the problem, if you can.
