Different kind of girl, my gf is confused?

ok so my girlfriends parents divorced a couple months ago and it really upset her and she's a very modest girl (like she doesnt like to show PDA in public or kiss in public or stuff like that unless we're alone) also the kind of girl that sorta keeps to herself when things are bothering her, even from me. So i know its been a couple months but ive talked to her and she seems fine but she hasnt said she loves me since then. and when i brought this up she said that she still really likes me more than a friend but she isnt sure if she loves me still but she doesnt want to break up. So im gettin concerned and i really am still in love with her and i tell her all the time but i dont know how to talk about this with her or what to do. any advice.
