I think the bad feeling everyone has about the seme may be because it seems like he's trying to recreate a relationship he had in the past that either didn't work out or was a highly abusive and/or toxic codependent relationship.

We can't forget what his "friend"/writer said. The seme has a habit of getting into sticky situations and it's implied that he comes from at least an upper middle class family so we can infer, if all that info is correct, that his first and following relationships have all been people wanting to rely on him for living expenses or wanting to spend his money extravagantly.

If we make the inference that the seme was in an emotionally abusive relationship where his partner relied heavily on his wealth and possibly tried to prevent him from leaving, then the seme might be trying to recreate that part of his life. Alot of victims of emotional abuse tend to get left out on the side of the road because their wounds can't be seen. And a huge majority of them tend to become the "toxic" partner when they get in future relationships because of the lack of care and treatment and that leads them to recreate their own abuse in an attempt to understand and heal.
