I need some advice...

So I was with this guy the other night. I went to his place for a pizza, wine and movie night. I had four glasses of wine and that's all I remember, I can't remember anything aside from the beginning of the night. As bad as this sounds, I can have more than 8 glasses of wine and remember everything from the night. The problem is I can't remember past a certain point. I do know that I was sick in the toilet. As far as I am aware I had the same amount of wine as the guy I was with. Im not all that concerned that he slipped something in my drink as he doesn't seem like the type of guy to a) slip something into a girls drink, or b) he wouldn't have needed to (if u get my drift ;)). I'm not sure where to go from here. I'm a bit embarrassed to txt him and a bit worried he won't want to go out again. Any advice would be great :)
