Oh, ferchrissakes. Do you not speak the English language? It really isn’t that hard. When “but” is used as a conjunction linking contrasting statements, it could not be any clearer that the second statement is the key.
“I wanted to go to the store, but my car had a flat tire (so I didn’t go).”
“She tried to dye her hair auburn, but it came out orange (instead of red).”
“I was hoping to win the lottery this weekend, but I didn’t have the winning ticket (so it’s back to work on Monday).”
“I still love you, but I can’t deal with any more hurt (so I don’t want to see you again).”

Against your four sample sentences, let’s compare the two examples provided to you by others:
“I love you, but I think you’re a repulsive idiot that gives me nightmares.”
“I’ll always be here for you, but I’m not going to volunteer to actually support you”
In each of your first three examples, the second clause explains why the attempt mentioned in the first clause was unsuccesful. In your fourth example, the second sentence explains why the normally expected outcome of the first sentence did not take place.
This is how we can understand your sentences as not involving a contradiction.
But I submit the two other sentences are more like this:
“Cat’s are nice, but then again, they aren’t nice at all.”
This is just a flat-out contradiction. The second clause simply negates the first. Neither of the two example sentences involve contradictions as direct as this, but they do express sentiments that are very nearly directly contradictory. No one “loves” someone they think is “repulsive” and who gives them nightmares. Similarly, it does not make sense to say one is “there for you” but does not “support you.”
