If he's a decent guy, he's not "expecting" anything, but chances are he's HOPING you'll still be there for breakfast next morning, too.
The question is what do you expect? Do you expect him to respect you? You should. This fourth date is going to play out like how you want it to.You might not have control on if it goes well or bad but you will have control on weather you stay or leave.
I wouldn't worry about what he expects. His imagination has nothing to do with you. Just worry about what your comfortable with and where you want things to go.
Each guy is different, some might expect a "little dessert" after that 4th dinner, others might not, but a way to anticipate what's to come is to talk to the girl you're inviting over beforehand about how you both would like the evening in question to progress...:) that way there's no awkwardness the night the dinner arrives....
Not much if you still live with your parents
If you didn't do what he expected on the 2nd there wouldn't be a 4th.
who cares what they expect, it's a really nice invite. i would go, and enjoy my self, and then go home at the end of the night untouched!
Has he been the one paying for the other dates? Maybe he's just looking for fiscal relief.
Now that would depend entirely on the guy..but you can bet your bottom dollar...there's sex in there somewhere.
dinner and talking
