For example I was 5 minutes late a few weeks and I got hell for two hours about that. The other day we got in an argument because I was supposed to call at 11 but I called at 12. Also I own a bearded dragon (a lizard) and she got mad at me because she was worried I had more feelings for the lizard than her.
The straw that broke the camel's back was when I caught her snooping through my wallet. She got mad at me because she says that I should have gotten mad at her then and there so that she would know that it's inappropriate to look through wallets (yes this is for real).
When I finally broke up with her she showed up at my house uninvited and waited for me for several hours (I actually posted about this on G@G)
The reason I am thinking of giving her a second chance is because she sent me quite an extensive apology letter the other day and she's a Japanese landed immigrant - relationships and all are a bit different in their culture.
