I don't think this is necessarily that the advice is getting worse. My friends are pretty mature and stable people and I've found that they've had way more issues staying in relationships longer than they should've compared to breaking up earlier. Especially for relationships earlier in people's lives (where many people I know has a story about being in a relationship for way longer than they should've and seems often to be the ages of people asking for advice) erring towards breaking up seems prudent.

Not that these relationships subreddits are good (often it's obviously children trying to give advice they don't have the experience for) but I don't think that telling people to break up more is less accurate advice.
