My advice is to relax......

Seems that you're looking for things to go wrong, forgive me for saying. Relationships are always up and down, esp when you live apart. You've both got your own lives too!

If you are speaking every day, you're hanging out when possible then I wouldnt worry too much. Sure, life gets busy, and it has for the pair of you (good luck with the interview!) but I wouldnt read too much into it. You saw him at the weekend, and you're seeing him tonight, wow, I'd say that you've got a keen one there!! Please dont fret, or see things that might not be there. Unless you hear it from him, then there's probably nothing wrong.

And please remember... if people start to drift, or pull away, or change their minds about someone, worrying about it will do absolutely nothing to help. There's nothing you can do to give someone that chemistry, and what will be will be. I dont think this fella is pulling away from you, just trying to say that worrying yourself so much will just not help you.

Enjoy tonight and have fun!
