My GF of 2 months won't let me see in her closet. She says it's very messy. I don't really care what's in it but this annoys me a bit. Also the other night while walking she dropped a mail in the post box. I asked what it was and she told me it was a secret. Wouldn't tell me what it was. She's not given me any reasons to not trust her, but I'm like WTF. I like her a lot but this has me rethinking how I feel about her. Am I overthinking or justified to be annoyed?
