" am disturbed and concerned by the general trend that the world seems to think all heterosexual relationships are inherently abusive or something. We hear a great deal about the bad, the things gone wrong, the dark side and sometimes it seems like there are no good examples out there, no discourse on "This is what a good relationship look like."

Exactly .... Since a majority of the relationships are heterosexual, relatively most problematic relationships are also heterosexual, that would kind of feed into the "all heterosexual relationships are inherently abusive" mindset
