I'm not going to help my boyfriend with college applications
Why would you not help him?
I am tired of him complaining, I do not want to do it anymore.
It is expected to help out people we care about, you should tell your boyfriend how you feel about his complaining. He should act like an adult and be able to fill out the forms on his own it is wrong to expect you to do it for him.
I think this will help him, I'm doing it for his own good.
It sounds to me like you are doing the right thing and this is helping someone you care about. Hopefully he learns from this.
