I don't normally do this, but if you're going to correct someone, make sure they are wrong first.
<<Bah! Incorrect grammer! Glad to see someone else is in the same boat as I!!!! it shouldn't be same boat as I it would me same boat as me.>>
The correct expression was "...same boat as I." The reason is that the sentence implies "...same boat as I am." Ask any english professor or gramarian. "...same boat as me." may be in common use, but it is not correct. Besides, it would have been nit picking even if the original had been wrong. The only reason I correct you is because the only reason you posted was to correct the original poster's grammar.
On to the important part, If your g/f has something important planned for the two of you, ditch Half-life. If you had Half-life planned for a while and your g/f just dropped this on you at the last minute, explain to her that you have been planning this get together with your friends for a while and that it's not just a computer game, it's a chance for you to bond with your friends. Good luck.
