I've grown up with my best friend and his brother. Never ever fancied him. He's come back from doing 6 years engineering work in Thailand and there's just something that I never saw before.
I Find him insanely attractive and I cannot function in his presence.
I'm not too bad in a group but I cannot talk to him directly even then. I go bright red and go blank.
I have tried a few times to talk to him one on one but we're both incredibly shy with each other and blush stupidly. It's now at the stage where I feel like my jaw is physically locked in place when I see him. I cannot speak!
I don't drink but when he was drunk he came over to me and kept hugging me 
I think he likes me but while I think he finds me physically attractive I've no idea if he's actually interested as he's only 26 and I have a child so I reckon that would put him off.
Should I just leave trying to chat to him and make anything happen?
