Unrequited love

I (22 F) am in love with my best friend (32 NB) and find them to be incredibly sexually attractive. Don't want to be open about my feelings because I don't want to scare them off. We often drink together, I'd hoped it was just the alcohol, but spending more sober time with them hasn't changed how I feel. It doesn't help that and is a source of increasing guilt that I will get the odd kiss from him, he is flirty, when substance affected forgets that we aren't dating and that he is very comfortable just wearing lingerie around me. Have the up most respect for him but feel very sad :/

Just go for it you only live once, I can feel the sexual tension between you too and you both need to release it
