You need to stop bedding down every guy who remotely looks like 'the one', take everything said to you with a grain of salt and step back and look at what you are projecting...if you can't simply have sex for the fun with no looking to a second time, you shouldn't be having it.
you say you've 'known' each other a 'few weeks', but how well? In what context?
Now that I got the preaching out of the way....
This only happened last night. You need to slow down, really and let this build naturally. If it's meant to be, it'll be right. If not, it should be taken as a lesson learned to apply next time.
(Personally, if some guy told me that dream thing, I'd giggle, say, 'yea right' and hand him the parmesan, cause that was cheezy
)
