Not sure what sort of abuse you're looking for, but this one is straight?

Also there's a couple BL ones that you might consider? Both completed, happy ending.

sekine kun no koi might be helpful? possibly. oyasumi punpun forces the reader to relate no matter what, so thats also a good one. there were times when i wished you were dead may also fit? im unsure, you might be able to find something by looking at the recs on this page https://myanimelist.net/manga/1162/Bitter_Virgin/userrecs i do strongly encourage reading "a cruel god reigns" even if it doesnt quite fit what youre looking for exactly
any manga with a kinda abusive relationship like where i can relate to the mc. preferably not too long, can be ongoing sorry ik this is weird but :((
