at a loss for words
You're hiding things from me. I know you are. If only you knew that I know it now. I'm slowly not caring anymore anyways. I just want to continue this friendship until the end of the semester because you do make things a little more fun here, i'll give you that, but after the year is over we can both go our own ways and have the fun we both want. What's so hard about telling me the truth? Even if it's not totally lying, only forgetting to tell me information, I still don't like liars. I won't be lied to, you picked the wrong person for that. Apparently I picked the wrong person as well. Silly me, now I know.
