It's been 3 days and you haven't even met him in person, how can you possibly know at this point whether you will have feelings or not?

It sounds like you both have gotten too intense too quickly. For me, if I met someone on a weekend I wouldn't even call them till Wednesday, to make plans for Friday or Saturday, and I would take it relatively slow for the first couple weeks.

Too much intensity too quickly clouds your judgement.

Then there is my sister who met her current girlfriend on a trip to Florida. They hung out for 2 days. The other girl came to visit foe 10 days and then moved in. I guess gay folk are on a whole nother level?
