Big Bang Theory...Spoilers in the first post

Clearly my opinion will be in the minority here and that's fine.  But I don't like Leonard and I really can't stand the idea of Penny tying herself to that cheating little hormunculous.  While I know it's not necessarily true that once a cheater, always a cheater, I don't see that he's changed from the guy who cheated on Pria or sabotaged Sheldon in the North Pole (and only went to retrieve Sheldon from Texas because Penny basically made him).  

And while I doubt the writers will go this way, it's my hope that Penny would re-evaluate the relationship after his confession.  If she still goes into this with eyes wide open that's one thing.  But I feel like she's there out of habit,  or because he's the best she thinks she can do, or she's afraid of losing her circle of friends, or because she's getting older and it's time to settle done, or because the acting thing didn't work out and she doesn't want to be a failure at this also, or because her Dad liked him.  It just doesn't seem like a healthy relationship to me.  But then again healthy relationships don't often make for good ratings.

As for Sheldon and Amy, I can absolutely see him as having a ring because he is a planner and he's looking ahead to what he sees as the inevitable endgame.  Things are progressing at his pace , Amy has played along, most of his social circle is heading that direction or already there and no doubt nudging him along, and his ego makes it difficult for him to allow for the variable of Amy finding someone else or getting tired of waiting.  Reasons for Amy having stayed for so long may be similar to the reasons I listed above for Penny.  She's nudging/dragging him along in this relationship where, at times, he seems reluctant.  Yet she's not moving on as so many others would have.  I think it's perfectly realistic that she's reevaluating and taking a break.  It's a wonder she didn't do it sooner.  But it's a shame it's happening now after so many years of him not being that into her.
