theres something Ive been meaning to tell you

Theres something Ive been meaning to tell you is an expression often spoken to someone else where you want to speak about something very important or a certain private matter that you feel is important to discuss with them. This has been used most often in relation to coming out as a homosexual to your children or other members of your family, but can be used in any sort of situation where you are telling something you have been keeping a secret.
