Sharing Our Innermost Thoughts

One of my friend’s friend is also a very good friend of mine like more than them we vibe a lot. Whenever we meet through that mutual friend I’m like super happy to meet him. He has also told my friend a lot of times that I’m a very special friend for him and he’d never wanna lose me. Now I think I kinda have a huge crush on him and he has feelings for our mutual friend and he would come to me share his feelings for my friend who has rejected him. I’m here suggesting my crush how to get my friend who has no romantic feelings for him. I feel jealous everytime I see them together and i feel horrible to feel like that. I hate this situation and just wanna move on but don’t know how to because we hangout together and it’s really difficult moving on when you see them together all the time.
