In a relationship, do you ever say things because you think that's what the other person wants to hear?

I've recently broken up with a bloke cos I thought he was a bit odd & not all that bothered, but now having spoken to one of his mates, he said that my ex bf was saying things I thought I wanted to hear. I.e. I say, my own space is important to me, meaning sometimes I like to be on my own. My ex bf says, this is not a realtionship yet, despite the fact that he was turning up on my doorstep every single day for a whole six weeks and staying over most of the time, and one could go on...
