it depends on time.  if there hasn't been much time, she won't know what to do and how to do it and will be more concerned about not rocking the boat than engaging you.  often times us unfaithful simply don't want to rock the boat and we don't engage and we pull back out of shame and fear. 

it depends on the help she's received.  she may not know that she needs and should do this.  much like what i stated above, she may not really understand that engaging you and showing value to you is what she needs to do. 

it depends on her heart.  she may not be able to right now.  she may have her own issues/bitterness/blockage/etc that's going on that's preventing her form being able to be vulnerable and engage her and reach out.  she may simply have so much going on in side she has no clue how to interact with you and engage you.  

again, i don't know a ton about your own timeline but these are some of the things that go on in the mind of the unfaithful.. not excuses, reasonings.  with the right help, heart and timeline, she can change and engage you and help fill the tank.  not on her own though without expert help will she arrive there. 

that's OK as right now, the love language is tough at every level.  but what help have you received?  what work have you done recovery work wise?  counseling?  bootcamp?  any online course at all?  you're going to need to do some heavy lifting in terms of what i call 'infidelity-specific' recovery work if you're going to get to the other side.  these gifts won't mean much if you haven't been able to do recovery work in terms of having a protocol to work through. sorry for the delay my friend.
