I think you need to move beyond TV, cuddling and kissing (perhaps you're still trying to be caring for her and afraid to be more persistent?) and get her horny. She will probably put up LMR but you have to start getting her totally wet, totally naked and start fondling her errogenous zones while she's active and not sleepy. Maybe don't rely so much on passively cuddling up on the couch with TV (caring for her) but try something more spontaneous and erotic like start stripping her clothes off as soon as you get home pinning her up against the door as you close it. Or if that is too risky tell her you'd like to give her a massage as soon as she comes over, set the mood (music not TV) and take off her shirt. Massage and then take off her pants/skirt/shorts. Growl her out and massage with your tongue. Switch her on with more authority and confidence. She dry humped you so she is interested obviously but Im not sure how you could have gone from that to her falling asleep! It's up to you to steer it away from just being company by being a bit more aggressive. Especially now as she will very likely be over the immediate mourning period of her uncle. Keep an eye on her menstruial cycles too.
In the meantime, pull back on needy texts and just continue to shine your happy confidence and encourage her to be more forward by not texting as much. Having a plan B is always good to re-calibrate your focus too.
