Should I meet this man who makes me feel special?

My partner of three years is hardly ever at home. He always comes in late from work and we hardly do anything together. He agrees it's bad but nothing changes.

I recently logged on to a chat room and met someone special and we talk and e-mail every day. We have discussed meeting, he knows my situation.

I feel invigorated and alive again. I do love my partner and I am afraid of what is happening.
