A) Your boyfriend/girlfriend has a name. Use it. Starting every sentence with “My boyfriend/girlfriend” is not cute.
B) You’ve been together 3 days but you have more pictures of the two of you together than the number of days you’ve been a couple.
C) You don’t love him/her. You love the fact that somebody can put up with how lame you are and actually date you for a hot minute.
D) You will probably break up before I finish typing this anyway.
