How should I proceed now? Is there hope?

Thanks Kara. I don't know if the affair is still on - he hotly denies it, but words have become incredibly cheap. I sometimes even think he's on the look-out for a new woman. He's got the ideal job for it : sports instructor with oodles of charm (not turned towards yours truly anymore, though). However, he's always popping up here, doesn't necessarily warn me. wants to see the children, needs an object from the house... It's so difficult to see him here and not be like in the past. I've told him that I've accepted he needs to live through something else, that he needs time and freedom. My problem is: how to act in the meantime, when I see him. Being light and friendly is so hard - I feel tense and sad.Should I avoid him, be scarce?
He's gone, but the marriage is still there, and I really want to grab every chance of resurrecting it.
