Yes those 2 things are definitely amongst what bothered her. And also we had 2 arguments in April and May. While the April argument was resolved very well (we ended up having an AMAZING makeup date and were closer than ever), even though the May one was "talked & sorted out", but from her point of view probably left a crack between us, which she later thought was a result of the age gap giving us differing views and values.
She is shy with people she doesn't know well, but VERY social and close with her group (about 8 friends) and they go out and do stuff alot.
Having thought about her actions and reactions since the breakup, I finally think I know what state she is in. Basically she still has alot of feelings for me, but because she's not comfortable with the age gap, she is forcing herself to suppress them until they gradually dissipate over time so she can completely get over me and move on. This is evident since she when we text or talk face to face, she tries to put on this demeanour that she's all ok, but when sensitive topics get touched on, she loses control abit and either gets all emotional or physical (excessive touching, hugging etc.).
I don't know if the state she is in gives me enough to work on, since I'm no PUA and have no idea what I'm doing, but I will have a deep hard think about my game plan and what to do from here on, and also the stuff I should say to her if I contact her.
