["Besides that he knows the guy likes him and is still having sex, he hasn't really done wrong though?? I'm actually pissed at those hating on the bottom because fact is people don't owe you return of feelings just because of sex."]
I would have agreed with such comments if the uke stopped having sex with the seme knowing the the seme likes him and would be suffering from him not reciprocating his feelings. It is just selfish behavior, and no amount of past trauma or whatsoever could change that fact.
People can react differently to traumatic events, but nothing can excuse the harm they commit.
Men who sleep around with many girls while knowing they have feelings for himm would be heavily criticized but not the frail, pitiful and harmless women/ukes who do the same.
I'm not condoning doing either (criticizing both parties for being whores and whatsoever), but the thing is: The seme is still suffering from the uke's deliberate behavior.
You can tell me, why should the uke care if he's making him suffer, and I'd tell you, you're totally right. And that's what makes his behavior selfish.
I don't mean it as "He is selfish for not returning his feelings", but as "he is selfish for prolonging his suffering without rejecting him and no longer fucking with him."
The next question would be "is it wrong to be selfish?", the answer is simple "no of course, everyone does whatever they like".
All this to say, (yeah I had to write all this introduction cuz nowadays, expressing opinions that are negative against ukes/w is simply blasphemous): I don't like the uke's behaviors, I'd prefer for the seme to find someone who would truely value him and let someone else heal that uke, although I know it would only depend on author-sama's good will and, spoiler alert, I know that wouldn't happen.
