Hello everyone. I met a man a couple of months ago, communication initially occurred only occasionally on the phone, made a good impression, intelligent, well-mannered, sportsman in the past, now building a career.

On the first date he brought me home and introduced me to his parents, introduced me as his girlfriend, put me in front of the fact that now we are "dating". On the second date he proposed to live together, and on the third date he literally asked me to marry him.

I can't understand his nature. It's unreasonable to talk about love at first sight, about any benefit either. The man erases the boundaries between us, says why wait, insists on his own.

He just laughs at my assertions that we don't know each other very well. I do not understand where he is in a hurry and what is in his head?

Help me to understand what made him make such a decision?
