Ok, so I am having a difficult time with my t at the mo- i feel like he doesnt care any more and I feel a bit neglected by him

Without boring you all with the details, does anyone have any advice on how to tell him what I need from him? I find it extremely difficult to talk to him, and the thought of just blurting out that i want him to care about me more, to be more available to me, to tell me things WILL get better. I want him to tell me that i am worth all the trouble i give him (unintentionally), that he will be here for me no matter what, etc. I just cant verbalise that to him, and I am too scared to write it down and tell him directly. Any idea how I could go about it in a more non-direct way?
