Pla help me find this manga

Ok. So I remember reading this really messed up omegaverse manga b&w where the uke's partner was ass, n left him after getting him pregnant. Their child grows up well n is really protective of his "mom" . The father comes back n the child has already manifested as an alpha. They have some tense father Son face off. I only remember this much.
The reason I said messed up was cuz the manga felt like it was going for some incest pairing. Now I'm not sure if the manga was still updating or I dropped it but I kinda want to know wht happened in the end.
Very low Hope tht ppl will know of this, but posting it here anyway.
