I don't think Suda truly loves him like your thinking. If Suda loved him then he would be willing to give him up because it would be better for Hinata. Hinata has a week mind and if he picked his twin brother and Suda went I'm not having that, I think he would just end up right back where we started in the beginning. If you truly love someone your willing to give it up for the better of that person.

Everybody have this cute image of love, but they need to know that love can be healthy or unhealthy as well. You can love wrongly, you can be sick and still love somebody. You can hurt someone you love.
It's not the correct form of love but is still love.
This guy had this kind of twisted and desperate love, but wasn't playing with him as He said. He really care for him and wanted to stay at his side.

Are you kidding? HE RAPE HIM” HE SAID NIT BUT HE CONTINUE TO FUCK HIM!!! HINSTA NEVERNLOVE HIM WAS SUDA SAYING THAT HE LOVES HIM.......ON THE CONTRARY HINATA REALLY LOVED HIS BROTHER WITHOUT HIS BROTHER SAYING SOMETHING TO HIM!!! SUDA IS A RAPIST HE KNEW HINATA SINCE HE WAS 16 !!!!! HE IS A CRIMINAL WHO TAKE ADVANTAGE OF HIM OF A SICK OERSO! THE BROTHER IS NOT LIKE THAT HE WAS FINE WITH HIM WITH A WOMAN OR IN LOVE WITH SOMEONE BUT THIS WAS NOT THE CASE HIS BROTHER WAS RAPE AND TAKE ADVANTAGE
Everyone is minsunderstanding him.
He has mental issues, not only the thrauma about everybody manipulating him.. He was mentally wrong since child.
Even the author mention it, He's retarded (not in a peyorative way, but in the real way) and maybe kind of autistic.
It's not his fault at all. Even if he looks like "normal" and functional... He is not.
