we normally don't crush for too long....not because we're flighty or anything like that but because aries doesn't like stagnant energy or situations....if nothing is happening, if nothing is moving forward with the crush in question. an aries guy might just move on....

and yes like alex said, deep psychological issues will not be immediately apparent upon meeting so we might not know right away if someone is a stable partner....:/ we have to spend more time with that person to find out....
