Hello aff people and friends! I just don't know where to let this out or who to ask about this so I went here hoping that someone can actually help me. I've been so confused and conflicted lately if I should confess or not to my friend.

Okay, so here is a little briefing. For months now, this friend who happens to be my roommate has been giving me mixed signals. She's a girl. I'm a girl. What we both know is that we're straight. But since we became close, I'm not so sure anymore. Since late last year, I have been developing these feelings for her. I didn't expect it because I thought I was only seeing her as a family, as a sister, a daughter. She's very sweet, clingy, and possessive of me. She would kiss me on the cheeks or brush our noses together. She would bite my cheeks, my arms, or my shoulder. She doesn't like the idea of me dating. She gets jealous of other people. She says she might not be able to handle it if I would have a boyfriend. I've always been supportive of her when it comes to her crushes and the guy she likes. But I was also very vocal about my disapproval with her having a relationship with any of these guys because I believe she deserves better than them. I thought I was just being protective but then I realized that I am in love with her. When she was hurting and depressed, she shut me out and that broke me. Then we were okay again. We fight a lot because of her jealousy, possessiveness. A fight can last from days to weeks. But no matter what we always end up okay after every fight. It hurts whenever I see her flirting with other guys. I didn't let her see it but  it crushed my heart into a billion pieces when she told me that her long time suitor and her were already in a relationship. I thought she wouldn't say yes to her suitor because she says she does like him but she doesn't love him. Until now she tells me she doesn't love him yet. Before, I didn't want to ruin the relationship we had. It was beautiful. So whenever a thought about falling inlove with her pass through my mind, I would always brush them off. I diddidn't want to ruin our good relationship and I was okay with it because I can take care of her and love her without risking anything. I just couldn't risk losing her. But then lately I started to confirm and realize my true feelings for her. It isn't just a sisterly, motherly, or friendly love. I am in love with her. All I want is for her to be happy and be okay. Even if she's in a relationship now, I know she is not happy and okay. She has depression and anxiety. The guy and her relationship with him are not helping with her state at all. I just want her to be genuinely happy and okay. I'll be leaving her in the Uni soon. I'll be graduating. I want to get all of this off my chest. I want to tell her that I am in love with her. I want to risk it because I don't want to have any regret if I don't tell her before I move out of our unit. And I thought that maybe after telling her, I'll be set free too. I could start fresh after graduating. I just want her to know before I leave. But what is stopping me aside from her having a relationship is her reaction. I'm not sure if I'm ready to lose her. I feel like I will lose her if I confess. And this is new to me. How would she take it if she finds out that I am not straight. I don't know what to do. Help, please!
