Title Help

Can someone help me find a manga?? Pls. You'd be a great help for me.
So I was reading this manga like a year ago or so when I was very astrayed from what real life was like.

It was like a timeline manga where they started as children and grew up. The main picture of the manga was them as children.

So the story starts when they were children. They were best friends I think. It all started when they became teens probs. The seme turned the uke gay and they loved each other like literally it was so cute you'd cry. But then the seme found a "lesbian" best friend. Then they were like what if they're homosexual feelings were just a passing phase so they "experimented" which ended up with the girl getting pregnant and the guy being who he is taking responsibility.This part is the reason why many people hated this manga including me. The uke gets left behin when he found out about this. Considering the fact that the seme had sex with the girl without the uke knowing and the fact that they(seme&uke) were in a relationship made this even worse. So many years passed and seme had a "happy" heterosexual family with a daughter I think it was. But then the girl was dying so it was just up to the father to take care of their daughter. Suddenly the heartbroken uke showed up. He cosplayed now due to the trauma of getting left behind. He considered the other gay people at the bar he was working as family because they experienced similiar things that happened to them. I stopped at this part cuz seme having sex with a girl is sooooo damn disgusting. But I think im mature enough now and can take on real life so does someone know this??????(
