>>123617609This is probably the author's first comic and it's slightly autobiographical, so the male protagonist looks how the artist imagines himself or like how he wants the audience to feel about him.
Based on that, I imagine if the author went forward with this comic, you'd find both parties are bad people but you'd sort of get that "I'm rotten due to external factors" bias on the guy, while the woman would just be inexplicably nasty everywhere you went.
With a good revision and some care, it could be a good black comedy, though. Two horrible people often come together because they share a cynical attitude. Problem is, if they diverge on certain opinions they become cynical towards each other. If I were to write it, I toy a lot with gradually revealing how these people being whiny and selfish all the time has eroded most of their meaningful relationships, and that's why they won't split, because they've destroyed everything else and they're afraid to be alone.
The guy would be on a path to suicide. The woman wouldn't know where she's headed. It ends with them finally splitting but I'd intentionally make it unclear what they do afterward.
