I agree completely with the CL. After two days, he doesn't know you at all. Not even remotely. If this were me, saying "I love you" and talking about marriage after two days would result in me ending it before it's begun. There's no bouncing back from that. A guy who does this has some real problems to work out, as has been said, either with insecurity or fickleness or an inability to control himself or understand his feelings.To love someone is to know them.

I know some people believe in love at first sight, or "just knowing" as soon as they meet their life partner for the first time, but it takes time for their brain to catch up and agree with their heart. Having an immediate connection is not the same as love.I think you should break this off now. I really don't think asking him to slow down or give it time will change who he is...

Thank you both for your advice. I got rid of him today, he is such an awful person and I feel sad for any girl not strong enough learn that as quick as I did. Luckily I only wasted a week of my life.....

A BIG CAUTION FLAG - CRAZY! If it really is love at first sight, a sane person would wait until they get to know the other person a little more. You are dealing with a crazy one there.....

I met one of these lately they are just trying to use your for sex too soon is my experience.  Run away!..
