So, I have a huge problem recognizing red flags, and another problem taking a hint that they aren't interested. But my biggest problem is being led on. It seems to happen quite a lot and i just wish there was a way i could tell when a girl is being serious or not. One example is a certain girl who would vaguely talk about what we would do if we hung out together, but every time i tried to set a date she had something going on. not like normal stuff, it was always very weird and very sudden, and im sure also very made up.   
Lastly, how to stop myself from falling for a girl when i obviously shouldn't, like if its a very close friend that i shouldn't have romantic feelings for, as it might ruin the friendship. How do i tell myself to not feel romantic towards a person, when it feels like it can't be helped. Don't know if it matters but i saw a movie with this close friend last weekend (a scary one) and we cuddled, even though she has a boyfriend who recently moved away. it seemed more than friendly, as i know some friends cuddle sometimes. is she hurting me in the long run by doing this? she knows somewhat about my issue with relationships, but not the true extent. should i bring it up? I dont want to make it awkward, but i dont want to get led on again
