Meng: The whole problem is that now there's the hope of her (ex?)-hb apparently turning over a new leaf and quite honestly, I do think that in her mind it's not just about love but maybe a very small part about wanting Mr P to really make good this time round? It's kind of like... a sort of worry that if you reject him when he was sincere, then she would not only have lost something that would be her ideal, but possibly discouraged him on the way as well. Agreed that she should take a break and really evaluate again her options.
About irontestler, I have little to comment, though I have to ask if our individual happiness is really so paramount, that we talk about loveless marriages as something to get out of at any cost? I'm not saying that everyone has to remain in a loveless marriage if they don't want to, just that I do think that learning to be content where we are can also be a form of happiness. But in the end, the most important thing for her is to do what she decides to do, and not look back from there.
