sooo what does it mean ?

I admit that I didn't engage in the relationship 100%, and now it seem she cares a little bit more than me,

but I guess right now we're doing really fine, we are both 21, we lost our virginities to ourselves, we have sex and we are both learning, and the rest is good,

so what does it mean when she wants me to open up ? what things should I say and what I should never say (as a man being required to be the hard rock for her etc)

THis is my first relationship and in the 1st month I was quite beta, but then I started working on myself and reading TRP so I tried my best to be alpha, and things got better, better sex, me not being needy and her caring more,

is it time to introduce again a little bit more beta or what? how to do it properly?
