I'm a little upset with my friend. She makes me feel horrible

We've been friends since we were toddlers and we're both adults now.

I love her, but I feel like she is constantly trying to put me down and make me feel like no guy likes me, but they all like her. She has wrecked any confidence I had left in me when it comes to men.

Last year, there was a guy that would come talk to us for a while and of course, she had made it seem like he was into her and I believed her. That's why I was really surprised when he asked for my number instead of hers. I could tell that she didn't like that, so I never brought it up or anything, because I didn't want to make any of us feel uncomfortable, but she would bring him up all the time. And she was being a little mean about it. She'd say that she knows this guy wanted a more serious girl and he doesn't care about looks. And that she is a bit loud and playful and he prefers quiet girls. That he obviously doesn't like me, he just wants a quiet, serious girl to have a family with and that's all. And she'd talk badly about him, calling him ugly and judging him a lot.

Another thing is that there is this guy that I've liked for a very long time. Before she knew that I liked him, she never cared for him or mentioned him or anything. But now that she knows I like him, she won't shut up. It's always "guess who stopped with his car and started talking to me?". And "guess who couldn't stop staring at me last night?". I don't know if she's telling the truth and maybe she is. It breaks my heart a little. Everything feels like competition with her and it's exhausting.

It's always about her. How every guy likes her and how they all flirt with her etc. If I get any attention from men, she absolutely hates it and you can tell. She will immediately start being flirty and doing anything to grab their attention. Only once did I try to tell her about a guy that had been texting me and she was very dismissive and said that this guy has texted every girl on the planet, which I know isn't true.

I feel like shit. I'm at a point where I've stopped trying and I'm convinced I'll be alone forever. I'm out with friends and they will mention how a guy has been staring at me or flirting with me or whatever and I never notice or believe them, because I guess I'm brainwashed into believing that no guy actually likes me. I'm tired of this honestly. I've been nothing but supportive to her. And the worst thing is that I can't imagine my life without her. She's like a sister to me. She's always been. It just hurts.
