Welcome!! I feel your pain!!
I agree with YGirl. Step back and take a few breaths. It generally takes 6 to 8 months to get through the infatuation phase of a new relationship. Until you can get through that, you really don't know what you're dealing with. Can you continue to see other people for a while and see him occassionally (like once a week or once every other week)? A 48 hour sleepover within a few weeks of meeting someone might be "too much too soon" and it's enough to make anyone crazy. You might be putting a lot of unnecessary pressure on yourself and him.... and you might be coming across as desperate!!
