You're all so optimistic! blegh!
The anime spruced up the "proposal" very well. Got all warm and fuzzy...
But seriously - isn't anyone even a little put off by how it ends!? C'mon!
"That means you won't cheat on me, right?"
*sweatdrop*
"RIGHT?"
*silence* *averted eyes*
<i>He probably will...</i>
So here we have a confession of love - something he does often, and to just about anything female.
Sure, it's unique in this situation because you get the vibe that he's being sincere for the first time. But here she goes and says she'll stay with him, be the mother of his children, and yet they're BOTH already consigning him to commit adultery. The ending insinuates that he isn't ready to be faithful, and that she is going to accept him, even though he'll probably cheat on her. And they just got ENGAGED.
See, I just disagree with pretty much all of that post.

Maybe I'm giving Miroku too much credit, but in the same vein, isn't it possible you're giving him too little?

Anyway, I feel like a good rant, so here's my take on it all...
First of all, Miroku's womanizing has never, ever been serious. For all of his lecherous ways, I even have my doubts that he's ever gotten past first base with another woman. (This is highly debatable, of course, but it's what I think.) As for the "Will you bear my child?" line, even you admit that episode 132 is probably the first time it's ever been sincere. In general, a lot of people seem to agree that Miroku's lechery is more of a way of pushing people away than anything else. Someone as bright as he is has got to realize that hitting on and/or groping anything female in the vicinity isn't exactly the way to win over a potential bride. It
is, however, a great way to demonstrate to said female how much of a jerk he is, and that he's not worth pursuing. The fact that he actually seemed to increase his womanizing habits after he met Sango (that, and the fact that she became his main groping target) always implied to me that he was making an especially desperate attempt for her.
Problem is, Sango wound up falling for him anyway, so his plan ended up backfiring completely--instead of driving her away, he only wound up hurting her over and over. The worst part is, he didn't seem to realize it for a long time... either that, or he was in denial. He figured that if he did quit the lechery and become monogamous for her, and allowed himself to fall in love with her and vice-versa, that there was too great a chance he'd end up hurting her even more in the long run, if and when the kazaana swallowed him up. Seeing as we don't know anything about Miroku's mother and very little about his father, it's possible he's got issues that stem from whatever happened with their relationship. Or it could just be that he remembers how much he himself was hurt when his father died. Either way, it's probably one of the main reasons why he acts the way he does.
So ok, we now have the set-up for Miroku and Sango's relationship during most of the series up to this point. One important thing to keep in mind is that we (and the characters) have seen more than once that Miroku really does care about Sango. He's willing to give his life for her--that certainly implies something big. Now sure, he's a decent guy, not to mention a monk, and he'd probably be willing to sacrifice himself for many people, not just her. But when it comes to Sango, he takes it to a whole new level--he seems willing to put himself at risk at any time even to prevent her from just getting injured. (He takes blows meant for her, he's gotten poisoned twice after using the kazaana specifically to help her, and so on.) Basically, he's always been much more concerned with her welfare than you would expect if they really were just "comrades" with the same goal.
So there's some evidence that he's loyal, and that he does care. Now, enter episodes 131 and 132. Miroku flirts with other women yet again, and yet again he hurts Sango by doing so. Only this time, it ends up going much further than intended, and Sango ends up being put in great danger specifically because he was out womanizing again. This is what we generally refer to as a "wake-up call."

Basically, Miroku finally realizes at this point what I mentioned a little above--that his plan has backfired completely, to the point where not only is it just stupid now, but it puts Sango at risk in the end anyway. Hence, he finally decides to come clean about his feelings, ask her the question, and more or less, finally stop pushing her away. (As for his hesitation when she asked if he'd finally stop cheating on her, I think Kuro has a very good point, and after thinking about it myself, I agree with her.)
All right... so basically, the point of all this is that, because of these reasons, I've decided to put my faith in the two's relationship, and believe that Miroku really isn't going to cheat on her anymore. I could be wrong (in which case Rumiko Takahashi is going to be hearing from me

), but that's how I see it. And I think this is how Sango sees it as well. She seems to be giving him the benefit of the doubt, realizing that if it turns out he's still a lecher with a wandering eye at heart, well... that's why they're only engaged right now.

But hopefully, whatever she saw in him that made her fall in love with him will turn out to be real, and he'll be true to her from now on. It's a leap of faith for Sango (and us shippers), but this stuff isn't always supposed to be easy.
Could be I'm just a romantic at heart.

But I do foresee a happy ending for them.
