I did.
A few silly messages, shared photos (non offensive), proceeded apprehensively.
We then started talking on the phone. Reached the point that we would watch movies together, from separate addresses, whilst commentating.
This went on for a month, or so.
We met, and it was scary/amazing/scary/ beautiful. We kissed on the doorstep. Best kiss ever.
That first night, he accidentally said he was in love with me. I reciprocated.
We then spent half an hour apart, to regroup. It wasn't normal for either of us.
He didn't want to drink, because he planned to meet and go home. I plied him with a few drinks, offering the spare room. He accepted, but somehow ended up in my bed. He held me all night, and it felt right.
2 years on, he's snoring offensively in our bed. 
We've weathered hardcore bereavements. My DCs adore him, and it's reciprocal. He almost died over New Year, and has had life changing surgery.
I love him more than ever. He feels like he is less of a man, but I was watching his fierce fight in hospital l. I frankly do not notice the physical changes. We just work. He is the man I love.
Communication is key.
He's the one, after several unfaithful men. I trust him, and he trusts me.
Not sure I'm on board for another marriage. He never married before, and wants it more than anything.
In truth, I would marry him in a heartbeat.
I'm not telling him that though. Not yet.
