What do you think my conversation with her?

The shut up comment is directed to you correcting her spelling..she needs to really work on it.Not your fault she's illiterate.LOL Just kidding.Look,uhm..no she didn't reject you,but she has a boyfriend.Just let her figure out that he's no good for her..and maybe she'll go to you.Keep contact with her in a friendly manner.Tell her that it bugs you when she talks to you about other guys.If she knows you like her,she's obviously trying to make you somewhat jealous.Plus,going to the beach isn't a bad date!What's up with her?!?!Don't waste your time..but if you do--best of luck!
