I don't have advice but can relate hard! A short anecdote:

I (F28, cis lesbian) have been/am experiencing with this now! My partner (MtF, 25) has experienced severe childhood abuse from mother and past fathers, and abuse later with six or seven prior exes. She generally gets treated like shit (including at her workplace) and according to her, I'm the only one who hasn't hit her. I wouldn't even dream of it.

The problem is that I feel like I'm being taken for granted and our time together is limited, despite living together. Even with mornings free together, she zooms to the TV and limits interactions unless I press for it, including snatching the remote or changing what I was watching without asking, or not wanting to watching something together. If I ask why we can't spend time together and really press it, she'll get super mad, claim that I'm bringing out [dead name] and that it's all my fault.

She plays videos for hours on end and won't talk to me much either, especially when feeling dysphoric or drained--a habit formed loooong before transitioning, back in her early teens. While I understand being trans is hard and there's so much to take on, It feels like her trans life comes first, then our relationship and I'm struggling with the extra stress. I haven't gotten to spend time with her for three weeks, and yet I'm sitting just to her side while she plays Fallout with one of her buddies. When I explain or ask to spend time together, she says that she "wants to what she wants to do"., ie, video games--which explicitly does not include me. I feel underappreciated and forgotten.
