I'm mad my girlfriend didn't tell me about her history of depression. Is it just me who feels this way?
Why are you judging your girlfriend for something she didn't mention? Are you not kidding around?
She always seems to have some history that I have to find out about from someone else.
Your girlfriend had a good reason for not mentioning her mental history to you because she was afraid of your reaction. Judging her for her omission is not correct. Forgive her for not telling you and find out how you can now support her.
Omission is still a lie if you ask me.
Judging your girlfriend for something she can't control is not very noble of you. You should just be supportive, understanding and stop the whiny style of being petty for her sake. Love one another and maybe she will support you too for your issues.
