Sure, Marines don’t marry, and their girlfriends, wives and fiancés are too low to be marriage material, you have to be very confused to be posting the things you have been posting.

According to you, with no substantiation, Marines are not part of the trend of fewer men marrying. There is nothing in the articles that say that.
As for my comment that Marines would know about marriage, the military divorce rate is already significantly higher than the civilian divorce rate, and in the Marine Corps in particular as of 2019, the divorce rate among female Marines (7%) is close to triple that of male Marines (2.5%).
The interwebs are full of deployed military members discovering their girlfriends, fiances, and wives were cheating on them while deployed. But you go on insisting that you know that Marines are are bucking the decline in men marrying, and are wifing and re-wifing the same women up.
