My boyfriend needs help with his college appeal and I'm going to agree to do so but then later say I forgot.
Do you have a reason for agreeing to help and then lying and saying you forgot?
I feel I will get more attention from him if he's not in college.
It is okay to want attention from your boyfriend, but you should get it by being supportive, not by breaking promises. When he finds out he will feel betrayed and it will lead to the end of your relationship.
But he's my boyfriend, he won't mind.
I think there's a good chance your boyfriend will mind and making promises you know you won't keep has a high chance of him feeling betrayed. You should also be supportive of your boyfriend, especially in his academic endeavors, as they will help him thrive in the future.
