Advice needed please!

I've been bumping into a male friend a lot just recently, we talk, have a laugh, enjoy each others company etc, things seemed to have gone up a gear lately and on Friday after a long convo he kind of grabbed me and gave me the best hug I've ever had, we kind of clung together for a long time ... It left me grinning from ear to ear and almost dizzy. It was lovely.

I'm not sure how to proceed now, I have his mobile number but I'm not sure whether to text him or not as I'm not sure if we're in the 'friend zone' or not and I don't want to mis-read the situation and wreck a good friendship.

It's also slightly complicated because he's not totally over his ex and I'm not wanting to get hurt again, we both have kids and he works away five days a week.

Suggestions??
