We then didn't talk (I wanted to get over him before I messaged him), then a month on he messaged me & invited me round to watch TV. I took that as "I want sex", so said I no, but I would like to catch up. He said he'd like to too.
I then messaged him asking if he wanted to meet for a drink & to let me know a day if he did. He replied & within that said "yeah I'd love to but are we just catching up as friends?". So I replied saying yeah I only meant as friends. Since then he hasn't replied.
I would love to be friends with him, but I don't really understand why he hasn't replied when he seemed up for it?
