Are you laughing or are you crying?
I once read some advice about boyfriends. To figure out if he's worth keeping, ask yourself if he makes you cry more than he makes you laugh. I've followed this advice and have found it very helpful in my romantic life.
But only recently have I come to realize that this advice should be followed when it comes to analyzing other relationships as well. In a certain big relationship in my life, I feel like I'm on a roller coaster. Overall I can't help but think of the low points and how they negatively affect my well-being, as well as my relationships with others. I would chalk up today as a day that this relationship made me cry. If I keep getting more of these days, I think it's time for me to move on. Of course, that's easier said than done.
UPDATE:
Since I couldn't sleep due to thinking nonstop about today's really bad incident, I created an Excel spreadsheet to help me analyze this relationship rationally.
In column 1 I put dates, e.g., June 23, 2009.
Columns 2-4 are intended to be filled with checkmarks, as appropriate. Column 2 is titled "My __ made me feel good about myself." (For other relationships, I'd label this "My __ made me laugh," but I'm being realistic about this particular relationship. It hardly ever makes me laugh.) Column 3 is titled "My __ made me cry and/or really hate life." Column 4 is titled "I couldn't sleep because of my __."
Column 5 is for comments. Entries for June 2-7 and June 22 included the comment "___ hell," and this comment seems to be very characteristic of this relationship, especially in the past month.
So far most of the checkmarks are in column 3, although I'm just going to keep in mind that the last two months have been particularly difficult.
