I think the character I'm talking about is a close friend to the main character but I don't think that that is the right manga. Thank you for trying to help though!
OH! After looking up a little I found a description of one of the characters in "Fujoshi Kanojo" that fits exactly with my description!

Thank you so much! (How embarrassing how at first I said it wasn't... （/TДT)/ Sorryyy)
Hehe no need to be apologetic and embarrassed.(⌒▽⌒) I'm glad that it was the one you were looking for. Unfortunately there weren't many chapters about that female friend and her bf, I really liked that couple, they were interesting lol. I wish there was a side-story about them. :(
While I was reading some manga, I remembered a character in another manga, though I can't recall the name of it. I had a read a story that had a fujoshi who was married (not sure if she was married, but definitely in a relationship with someone and also, she's not the main character if I'm remembering correctly) and her husband found out that she had read yaoi after finding a book under her bed. I don't remember much of his reaction to it, but I think he told her as long as you keep it out of my sight it's whatever. To his reaction, she was infuriated and so she made a doujinshi of her husband getting rape by his computer cords and sold it at a comic convention. It feels so familiar and that scene is so vivid in my memory but I just can't figure it out. If anyone knows, please leave a response~(づ￣ ³￣)づ
