Yes theres a chance it could be a very uncomfortable angle/feel for your friend and destroy/distance the friendship however she might also say ‘wow/leftfield/never considered this but the answer is there/spoke to friends and I had a gem under my nose all along/lets give it a try’.
She might also see you as just a friend.
However if it was me there is noway I’d leave it/procrastinate any further.
I did this. Met a girl when I was 13, best friends. We even went to the same uni 300miles away- she had given me subtle hints (that I now know but couldn’t spot at the time) and I did nothing..
Idiot. The one that got away.
Live life with no regrets. Speak your mind.
