HEEEEEELP!!!

So, there was this yaoi I read YEARS ago (maybe 5 years ago) and I want to read it again but I don't remember its title ╥﹏╥!!!
I just know the seme was blond and the uke black haired. The uke was a salary man, and he was heartbroken because his girlfriend or wife left him. Or maybe he was just having problems with her, I don't know anymore!!! But the seme was taking good care of him, the seme moved in with him/was living with him. And the seme fxcked him everytime the uke felt down because of his girlfriend/wife (without consent at first but as always the uke ended up liking it). At some point the seme had enough of being used by the uke to get rid of a bad mood and rode the uke instead of fxcking him. Then he left, like, for good. The uke got super sad but they reunited after some time. If it can also help :
The wife (I think it was a wife) was also blond.
It's not really a funny Manga, it had a more mature/serious aura to it
The drawings were soft. The lines were thin, not thick... I don't know how to explain it better
Anyway, this is really ALL I can remember from this Manga. Please heeeeeeelp!!! ╥﹏╥
