<p>This reminds me of an old song by The Police called "Don't Stand So Close to Me".</p>
<p>Here are my stances on each:</p>
<p>College student + college student (age not a variable): To me, it's like developing minor leaguers. When they get drafted by a team, they vary greatly in ability. Some will make it to the show while others will fail to get out of A-level ball. You get some who can almost go to the bigs immediately. We'll use pitchers here in our example. Just as someone may have a 92 mph fastball and a pinpoint control slider when they are first drafted, someone may have the maturity to handle dating. On the other hand, you also get the guy who would throw three wild pitches, commit a BALK, walk two guys, and give up a fat one in his first inning of rookie ball. That guy is the one who likely won't have a real romance. You also get the ones in between who may show signs of having a love affair but nothing ever comes about.</p>
<p>In short--take a look at a ballclub's draft from a while back, say 1992. Only a handful of the guys they draft made the majors, and check on the track records of those guys. Some were legit players and others maybe lasted a few games and couldn't perform at all. This is what it's like at the end of the four years of college.</p>
<p>Guys and girls both seem to have this problem. I've found no difference in the two genders as far as maturity goes--you have equal numbers of major leaguers and career minor leaguers.</p>
<p>College student + high school student: Here's one for thought. This varies on what the circumstances are. If it's an old relationship that carried over from senior year, the key date is nine months. If it's still going strong by May (end of freshman year) it should survive. This is somewhat rare unless the student is a commuter to a local college. Typically it is the college student who finds new romantic partners.</p>
<p>If it's a student at a college who starts going out with someone who they knew in high school, this is even rarer. Another case is where a college student meets a high school student from a different high school through some non-college-sponsored club. This too is rare.</p>
<p>The high school relationship is very rare but seems to have the highest success rate in the long run.</p>
<p>College student + person out of college: This is often the byproduct of a student whose significant other graduated. These sort of relationships often will work. What usually doesn't work is when someone is in college and the other is in the workforce.</p>
<p>College student + professor: FLAT OUT WRONG. Look at the posts above me for more information.</p>
