Case of the disappearing engagement ring

No, not mine since I don't have one. One of the boys best friends recently got engaged. We will refer to the newly engaged couple as Choco and Cheena. Here's some background on their relationship. They live together and have (what I'd consider)somewhat of a rocky relationship. They are fighting/bickering constantly. They both get jealous easily and they keep each other on very very short leashes. They are probably the most co-dependant couple I know. Because of all this, Choco has had his reservations about getting married. He's always complaining to the boy about how Cheena gets "crazy" when they fight and that she is spoiled and lazy. He wants her to change before he marries her *cough* yeah right *cough*. Choco bought a ring for Cheena awhile ago and Cheena was aware of this. Choco finally gave her the ring for Christmas, but she's supposed to not wear it. It's like a "secret engagement." The other night the boy was with Choco, Cheena and some other friends and Cheena was wearing the ring. One of their friends said congratulations to them and Choco just brushed it off. Yesterday was the first time I've seen Choco or Cheena since they got "engaged." I was excited to get to see her ring, but she wasn't wearing it! I didn't want to ask about it because I know it's kinda sorta a secret and they don't want a lot of people knowing. I suspect that she purposely didn't wear the ring in front of me because Choco probably didn't want me seeing it and asking quetions. Is this not the strangest engagement ever? If I was Cheena, I'd be a little upset. I wouldn't want to hide my engagement. She should be able to proudly wear her ring and share the good news with everyone she knows. I love Cheena and think she's a really great and fun girl, but I don't know if these two should be getting married . . . at least not yet.
