The sister in law and her fiance going on trips abroad while the speaker is struggling to get their bills paid implies that the former are more wealthy than the latter and hence it is sarcastic to say that the speaker is grateful for it.
Context: My sister in law and her fiance are taking all these trips abroad and we are struggling just to get our bills paid.
Hypothesis: It's making me feel so grateful how my sister in law and her fiance are able to go on all these trips abroad when we're just enjoying the struggle to get our bills paid

Is the hypothesis incorrect? (Yes, no, or unknown)?
