Well my first thought is that you are still in the New Relationship Energy (NRE) stage, (infatuation) and it's hard to tell what you actually want long term versus what your hormones are telling you.
Are she and her husband trying to fix the marriage? If so, I would suggest breaking communication and letting her focus on that. Tell her you'd love to hear from her when she's ready, and leave it at that. If you don't, there is the danger that your influence will play a part (or even just a perceived part) in breaking up her marriage, and that could be a problem between you two in the future.
(Incidentally, if you're not talking to her, it implies that you may be talking to someone else, and thus makes you more desirable.
All this should be taken with a grain of salt, I don't know enough about the situation to guarantee that this is good advice, but I think it's a good start.
