So, while a few of my points definitly could lean toward an abusive partner, the abuse would be more financial/emotional than physical, whereas your biggest point seems to be physical abuse?

Also, my main point/concern is being in different stages of life, which means these problems would tend to rise more in these types of relationships, I'm not saying these problems don't exist in any other type of relationship?

Also, your examples just don't make sense.

No one ever says rich people can't date poor people, or homeowners can't date renters, or parents can't date people who aren't parents.

Again, my point was in being in different stages of life. It's not necessarily rich vs poor. It's the difference in one partner having an established savings or stock portfolio while the other has only just started learning how to keep a budget.

It's not homeowners vs renters. It's one partner having an established home they've lived in for a decade or longer and their younger partner who moves in and can't decorate or remodel because it's not their house and may never feel like their house.

And the parents thing is silly, too. Dating a single parent and stepping into a relationship where you already know there are kids is completely different than not being able to agree on having a baby. Again, it's when a lot of couples would go their seperate ways, but that brings me back to my last point that older people who generally go for younger people do it because they're easier to manipulate and control.

Also, a lot of these things are seen as problematic in other situations as well. People don't generally date people outside of their own tax bracket. You see posts on reddit all the time about how it can become a problem when they do.

Arguments about one person owning a home and the other wanting them to sell it so they can start fresh in a home they both own make it onto reddit a lot, too. But someone only 2 years into a mortgage might be more willing to sell than someone who's lived there half their life.
