Well, I could love someone after knowing them 1 month. It depends on what kind of personality they have. As far as wanting to marry them or get into a commited relationship, that is a different level of love.

I love some things about all women. They are usually the tender ones.
Try to find out what he means by saying he loves you.
You could be having an over reaction to the phrase.

Some people are just naturally loving and it is easy to love them.

I love my wife and I've been with her 35 years, however, I also love some other women but not with the intensity I love my wife.

Just my opinion so, take it for whatever it is worth to you.
