So there's this girl that I've been friends with for a while now, we've been chatting and texting for some time, the thing is that I started to catch feelings for her, and I'm like 90% sure that she knows that I love her cause pretty much our whole friend group already know that , cause the last few days we had before vacation I tried to spend it with her, we hang out we chat , hell I even tried to give her signs that I do love her, as I said I'm pretty sure that she knows how, so idk if she just doesn't see it or don't want to see it, I just want to confess my feelings to her, I'm not waiting for her to return the same feeling, I just want to get it out of my chest, but I don't want to ruin the very good friendship I've got with her cause I truly value it, so should I take the risk and tell her, or keep it to my self till the end?
