Please please please don't flame me! I'm posting because I need some advice.
For the past year or so I've been a member of a local group which meets every few weeks. I don't want to say what the group is, but it is a hobby group.
From the start, me and this married man hit it off (let's call him Tom). We have lots in common, the same sense of humour, etc. So, we are pretty good friends. We text a lot about our hobby, and other things related, but it's all innocent.
He is married with one child. I am single, no children. I haven't met his wife and don't know anything about her. He never mentions her.
In the past month, I have realised that I like him as more than a friend. I fancy him, a lot. I can't stop thinking about him in a romantic way. My heart flutters every time he texts me.
I know that this is dangerous and that no good can come of it. I have (with a heavy heart) decided that I need to stop being friends with him for both our sakes.
How can I end our friendship without telling him why? Or do you think I should tell him why?
