Compared to other promos, this one has a translated novel (๑•ㅂ•)و♡☆ https://...

Since it stopped updating and you want something near like it (the 1,000 something lives) you could read this (and it's continuously being updated/active): https://www.novelupdates.com/series/a-thousand-years-of-separationtoday-i-shall-be-the-villainesswn/

Sksksk i cant find it and forgot title no matter how hard i search (ノಠ益ಠ)ノ彡┻━┻ mayb you would be able to tell me huhu (*꒦꒳꒦).... Another could be manga about rebirths and sht is the story where the girl receives her memories with her loved in so many past lives ending in a bad way and as for the present life, ml became the hero and mc found work in a seamstress shop in the capital since she planned to end the relationship - then drama and action ensues then some little twists then happy ending

I believe this is the one you're talking about http://www.mangago.zone/read-manga/this_time_i_will_definitely_be_happy/

Bless your kind soul!!! (´༎ ʖ ༎ `)♡ Yessssss that's the one sksksksk so happy for the title haha i gave up and never thought I'd see it again soon after repeatedly tried searching for any trace of it in google and when that didn't work i tried mix and matching the genres huhu ;; wasted a lot of time.... So, thank you very muccchhh
