From my kids’ friends - most either amicably/mutually broke up the summer before freshman year, OR stayed together and then one of the couple broke up with the other some time during first semester freshman year.
A couple are still together several years into college, but those are the exceptions.
None chose the same college as their gf/bf, most it didn’t factor at all, but a few did choose the geographic area of their preferred college to have the ability to visit the other.
