I understand that you're angry with them. Again, they kept something really big from you and you wished they'd just told you. However, they're not mind readers. They can't know what the right answer is, or that you would have preferred to have known right from the beginning. Chatting with them is the best way to find out why they kept such a huge secret from you.

You don't have to talk to them face to face as I know that can be extremely hard. You could write a letter to them explaining how they made you feel, and how you'd just wished they'd told you from the beginning. Alternatively, even a text message or an email with your feelings. That way you can get your message across to them, and you don't have to approach them to do it.
