What does it mean when a girl touches my shoulder

it was not long ago when I was feeling sad a girl approached me and she gave me a pat on my shoulder and I dont know what it means when girls touch guys in the shoulder when they're feeling sad what does it mean

When I do it, it's because I'm trying to help you get over your sadness. If a girl pats you on the shoulder when they can tell your upset, than the girl does care about you. But that doesn't necessarily mean that it's in a love kind of way. Most girls are very affectionate creatures and do not like to see other people down in the dumps. She may like you, but if this is the only thing she's done to make you think she likes you, then I would wait for another sign. She may have just been trying to make you feel better.
