Ok...this is what I think.
I'm assuming this bloke is > 30 since you say you've been a LP for over 14 years..I assume he's of similar age.
So if he's in his thirties and he's never lived with anyone then my guess is he's either gay.....or has low self confidence with women.
Now assuming he's not gay and looking for a woman so he can appear hetro then he lacks self confidence. In which case this may explain why he wants to go slow.....in case you reject him.
I think he's interested. After all, i don't go texting my mates (even female ones) after a night out that I had a great time and hope we do it again. That sort of text is usually reserved for a woman you like.
My suggestion is to escalate things slowly. Have you held hands yet? If not, try linking arms to start with....later hold hands. Basically you increase the intimacy bit by bit. That way if he's not interested, you will get the signal without having to put yourself out there (IYSWIM)
You say you've hugged and he's kissed you on the cheek. Next time, get the hug, take the peck but don't let go so quick. Hold onto him for a bit longer than you should, turn your mouth towards his, take a breath and wait.....
If that's not a big enough hint and he still doesn't go in for the kill then you really need to question whether this guy is for you!
Oh and before someone starts bitching about my gay comment, i was talking to two women last night. One who was asked out by a gay guy, another who married one. So it does happen!
