I guessed so because I lost 6kg in the critical 6 weeks.

stupid, pointless, ridiculous feelings.

I didn't consider my feelings stupid or ridiculous.

Hate would have been stupid because it would have destroyed too much for no comparable reason. Excessive jealousy would have been ridiculous but the jealousy I felt was appropriate. I considered polyamory. I didn't rule it out on moral grounds. But my feelings of jealousy about their behavior didn't allow it. I don't know whether it had been different if she had loved us both equally. Most astounding was the feeling when I gave up my love for her; when I realized that in truth she didn't love me. I could feel it leaving me in a few days. Strange.
