<human>: Probably a little different than most proposal topics, but rather than wondering about whether I should propose, I'm already comitted to doing that. We've been dating about two years, I'm waiting for the ring to be made and come in, and I'm planning to propose this summer. We've talked about getting engaged, and she knows it's going to be this year.

However, the issue is that she keeps asking nearly every day when I'm going to propose. I've told her that she will only find out when I actually propose and that she shouldn't be asking me about it. She keeps asking out of excitement on her part, but it's stressful for me when she keeps asking because it keeps creating this expectation that I should have done it yesterday. This isn't her intention at all, but it's adding to my stress regardless. 

Now when I try to bring this up, she then says she feels like she's being punished for being excited and doesn't understand why. It never really feels like my point gets across that I'm asking her to tone her excitement down just a little because the way she is showing it is adding uneeded anxiety to the largely normal nervousness that comes along with proposing. I've largely presented this to her as I've done here, she feels bad, and nothing changes for either of us. 

Any thoughts on how to tactfully get this point across? She used to be easy to talk to, but after we realized we're definitely getting married in the future, she's caught the wedding fever bug (Pinterest, etc.) and it's very difficult to get her to talk about much else for long.

Condense the text into a few key points
<bot>: My girlfriend is overly excited about when I will propose and I'm feeling unintentionally guilt-tripped every time she thinks I'm going to propose. Any tactics for getting someone to contain their excitement for awhile?
