Lost, I've been having the same thought, sadly. Mutatio is correct. It would be a mistake to act on it, tempting as it is. There is the matter of personal integrity. My H did a temperature check yesterday on the same subject....probably to make sure I was right where he left me. On one hand, I really want to hurt him back. But on the other, I have to live with myself.
Right now, I like who I am. Pretty sure I wouldn't feel the same about myself if I started acting like H.
Just want to say, I truly understand the thought and temptation! Just don't think it would be a good idea to do anything about it.
