It's alwase very hard to let someone else into "YOUR" world so to speek. Take baby steps and do whatever you need so that it doesn't feel like he's invading your space. If you think he is curious about stuff and you think he is going to ask about things.. have you thought about what you will say? Maybe planing ahead your answers or just how much you are comfortable telling before he askes will help with the stress for you. I do think its normal for people to be curious about the person they are interested in.. sort of the saying.. I want to know ALL about you!! but if your worried about pushing him away kind of thing then pick and choose what you want to say.. and if its to personal just say you arn't comfortable talking about it right now and I'm sure he will understand. and only time will tell if he stays the same!! so have fun and enjoy that time it takes to see him for who he is!! Can't wait to hear how Friday goes!! Hope it goes well and you have another great night!!
