ADVICE NEEDED PLEASE!! THANK YOU!!

Okay so here’s whats been going on. I have liked this guy named Blake since November 2018. He’s really sweet and really nice to me and he’s hilarious. He’s also my main guy friend that I see everyday and hang out with. But he was dating my best friend Cloe at the time, so I didn’t tell her of my crush obviously in fact I didn’t tell anyone. Then in February 2019 they broke up. At this point I really liked him but wanted to give him time to move on and I didn’t want to hurt my friend either. Later in February I was talking to my other BFF Bella and she said that he has a crush on someone already. The she said it was her. I wasn’t surprised at all. However later that week I told Bella that I really liked him and have liked him forever. Then some more drama came into the mix and Bella broke up with her bf. I told her to date Blake because they both really like each other and it would make Blake really happy, which is what I wanted for him. But she didn’t want to because she knew how much I like him and how much I wish I could be with him. But I knew he wanted to be with her more than anything. So now they’ve been together for nearly a month. And it’s really hard to see them together but at he same time I’m really happy for them. SOO after the background info my question is how do I get over Blake? I still really like him and wish I was with him but unfortunately I’m not.

Thanks for the advice!
