No, I was just giving mine some more thought. It's hard to think when I'm at work.
It's a tricky one because I've been in similar positions before. I really don't know how I'd react. If things get to the point where we're doing that, the relationship wouldn't last anyway. It probably had failed some time ago and we just hadn't admitted it. If I cheated on someone it would be because I wanted to leave them and didn't have the courage to do it alone.
With my last girlfriend, things were bad for years. I wanted escape routes because I couldn't bare to leave her and be alone. I actively tried to cheat on her at one point, after I'd already decided I was leaving. The silly girl I made a move on was too bloody blind to see my interest, and I knew she was interested and she knew I was interested. I didn't end up leaving her after all. Then my girlfriend went and did exactly the same thing, but succeeded.
After that, we did remain friends (under shakey circumstances). Eventually, I fell in love with her again and found a way to win her back. Why, after all the [nocando] she put me through? Love sucks sometimes. So that lasted another 10 months before she went and did it again. She's not worth the trouble any more.
The only thing I wanted after that was for her to find out what it was like to lose all your support and have to learn how to cope by yourself, and not just bounce from boyfriend to boyfriend. I don't care for her anymore, just that the five years we had together isn't in vain.
