Hi a few months ago I accidentally found out my really good friend is a lesbian. I was house sitting and used there computer and after I was done I went to delete my history as I always have I noticed something about lesbians and tumblr. I know it was wrong but I clicked it and there was her profile saying she was a lesbian with a girlfriend. I was surprised because she has never said anything about it and acts like she is into men. I feel really bad for her because I see how happy she is on timblr putting pics and vids up of her and her girlfriend while she is visiting her right now. And I really want her to know she can trust me and I will support her and I'm happy for her. I couldn't imagine having such and big secret and having to live a secret life. She is going off to college in the fall and I really don't want her to leave and not tell me about her girlfriend. That would hurt my feelings she doesn't think I'd support her. So basically should I tell her I know or what? If I should how should I go about it? I'm 21 male and she is 19 we have been close friends for like 8 years.

No. Don't say anything about it. When she is ready she will reveal her secret to you. When she does... be supportive.

There is no proper way to approach this with her so it is best to sit on it and wait for her to feel comfortable enough to say something to you about it.

Let me see, tell her she can trust you, but confessing to snooping around in her computer history.

If and she she wants you to know she will tell you
