Last week a man approached me in the gym to introduce himself and chat, he seemed pleasant so when he asked to take me out some time we exchanged numbers. I'm not really looking for anything but wouldn't have minded dating.
He text me the following day and after a few minutes of benign chat and him saying he wishes he could be here with me
this followed..
"Let me tell you something, I want to be honest to you"
I replied go ahead..
Him: "I'm looking for a serious relationship. Are you ready for a relationship? If we like each other?"
I replied saying I couldn't possibly answer that as we hadn't so much as had one date 
He then replied saying "Yeah that's why we should meet up soon. I was just saying that to let you know"
He then asks if I want more kids (I had told him I have 2)
I reply in humour and say maybe in a decade or so but definitely not anytime soon. That kills the conversation stone dead as he replies "ok" and then nothing since.
Now my AIBU is:
AIBU to conclude that he was just angling for a quick shag, and that he came out with the speal about looking for a serious relationship because that's what he thinks women want to hear.
The asking me if I want any more children was, to me, him trying to ascertain whether there's any chance of him having unprotected sex with me any time soon.
Given that I wasn't receptive I'm hoping he doesn't bother approaching me again if I see him there tomorrow.
Am I too cynical or do you agree with my suspicion?
