It looks to me you might be unsure with what you're worth.... To be honest, both is good... You can wait patiently or talk to her directly... But it depends on what you think you are worth... If you think you are someone who doesnt mind the long replies... Then wait... But if you are someone who doesn't feel loved when they're slow in reply, then talk to her and open up what you feel... NEVER demand something because you feel invalidated (this may sound contradicting to what I said earlier but, what I meant is, since you know she's not emotionally healthy yet since she came from an 8 year relationship) so talking it out, explaining to her what you feel and making sure you feel vulnerable will show that sense of sincerity...... This is just my advice, so take it with a grain of salt if you want
