I like dark , dangerous lovehate kinda stories
Something psychological and dramatic where there are obstacles and hardships in the relationship. Jealousy and possessive lovers are always nice as well .
I prefer completed. long manga (2+vol)
(No shota/lollicon plz its just not me )
Try "Yuuutsu no Asa" by Hidaka Shoko. It's not psychological but it has it's certain dark aspects through out the story. Dangerous lovehate relationship. It's long with 28 chapter(vol.6). Not complete though.

If you don't mind supernatural thrillers, Uki Ogasawara can craft some dark stories: http://www.mangago.zone/read-manga/urakatana_kami_no_ki/
and http://www.mangago.zone/read-manga/nightmare_fortress/ —although watch out because she can slip over into pure camp sometimes, with results that are more hilarious and WT
(old computer) WTF instead of dark and transgressive.
Then there's Ike Reibun with Bi no Isu: http://www.mangago.zone/read-manga/bi_no_isu/ , and its side-story, http://www.mangago.zone/read-manga/kobi_no_kyoujin/
Almost anything by Inariya Fusanosuke, http://www.mangago.zone/read-manga/giglio/ or Mizukami Shin, http://www.mangago.zone/read-manga/aigan_shounen/
Awesome story! Great story line very touching.
Being afraid to love again is hard. Being able to overcome that fear is something that requires courage and strength!
