I'm in love with my best friend and it is causing me a lot of pain

So I have been close friends with this girl for about 10 months. A few months after meeting her we got to be close and I fell in love with her. I have told her about my feelings once and we had a fight and didn't talk for a few weeks. She said I'm just infatuated with her and I can't love someone that doesn't love me back. Truth is I am 28 and she is the first girl I have ever had strong feelings for. Anyways we are still close friends but now she is starting to see other guys casually and have sex with them. This is destroying me and getting into the way of our friendship. She feels the need to tell me about the other guys and sex and asks me question basically treating me like I'm her gay best friend. Her and I have never had any physical contact. She knows how I feel and that I am highly attracted to her. There is a catch though and that is that I am a virgin and she is far from it and I know she doesn't like it. This scenario is putting me in a very bad depression. It's bad enough she doesn't want to date me but she won't even have sex with me and i'm a better looking guy than the one she is seeing. I am so confused and hurt and have no idea what to do....She means everything to me. I need advice from someone who as been through this

Hello. I'm sorry you have to face the struggle you're facing now, it can be really hard. I'm female, but I was in your shoes and had seen this situation from both sides. First of all, I don't think your feelings are any less valid just because she doesn't love you back. When it comes to love, people have different outlooks, and her opinion about love is based on her own experience. It may be difficult for her to understand you if she never experienced one-sided love, but it's certainly not your fault. She may also fail to understand she's hurting you badly when she talks to you about her sexual life. I'd suggest to tell her it really bothers you and makes you depressed and ask her not to discuss her personal life with you. If she's really your friend, she will understand and try to be a little more tactful. Refusal to understand you may be a sign that she does not respect you, and it would be better for you to get her out of your life, even if it's going to hurt. You should understand that you may be kind, good looking, smart and overall a great person, you may be an amazing potential boyfriend, but you still may not attract her. Love and attraction are irrational, and if she cannot like you back it's neither your nor her fault. You can ask her not to shove her sexual life in your face, but she has a full right to control her personal life and decide whom she wants to date or have sex with. And if it bothers you so much that you can not just be friends with her if she is dating other guys, I'd suggest to be around her as little as possible and do your best to move on. After all, you can't blame her for seeing them, it's not like she's cheating on you. Currently you have two options. You may either stay with her as her close friend and try your best to get over your jealousy and be a good and supportive friend, or you may choose to break off your friendship to avoid being hurt and and just try to move on without her. I'm sorry to say this, but it's not going to be easy either way, and regardless of what you choose, you'll have to be strong. I wouldn't expect she'll eventually change her mind and decides to date you, although it's not entirely impossible. Regardless of what you choose to do, I wish you best of luck!
