They'll do what a lot of people who vote right-wing (not all) do now. Act controlling, and try to stop them from talking to other guys.

In my case, had an ex-husband swerve at me when I was driving. Dating another woman who the guy has managed to fully isolate from her original friendgroup including myself. He's dropped statements to her such as mentioning he knows where I live, etc. Had another, who decided to threaten me mafia style

Or, ban abortion (which they have already tried to do), so they're forced to carry their kids. At this point of time, surely any guy voting for MAGA (at the very least) should be considered a huge red flag.

And amongst all that, they'll keep blaming everyone else for anything they can

They're already in support of child marriages.

They will try to push legislation and cultural norms that pressure women indirectly into marriage. They will try to make being a single woman less pleasant of an experience. Shame them culturally, cutting funding for single mothers, making childcare more expensive, making workplaces more hostile for women to work in, etc.

Many of these things are already in the works by conservatives, they will continue pushing them forward.
