<human>: First off, I want to say that I am no means in a rush to get married. We're completely happy simply living together for right now and enjoy life as it comes to us (some recent events have brought to light the legal benefits of being married, but we don't want those to be deciding factors).

We've talked about the future multiple times: getting married, buying a house, starting a family, etc. He's brought up the conversation too and seems genuinely excited, so I know it's definitely our plan. However, it's always just been "someday". For him, "I'm coming home soon" could mean five minutes or five hours. He's not very concise with things like that, so I have no idea what "someday" means to him.

I've thought about just flat out asking him what his intentions are, but I don't want to put him on the spot or ruin any potential surprises. I'm not talking about knowing exact when and where and how and whatever that he's planning to propose, just a general time frame. 

We're planning a trip across the country at the end of summer to go backpacking for a week with friends. It's something we've both wanted to do for years and we finally get the chance to go. Personally, I think at the top of one of the mountains would be the absolute perfect place for him to ask. I've hinted to him this as well, so he's aware of the idea.

If he's planning on asking on this trip, great! If he isn't planning on anything this soon, that's fine because it will still be an amazing trip. If he wants to wait until I'm completely done with school (I have to at least get a masters and I'm finishing my bachelors up in a year or so), that's fine. Anywhere in between works, too.

I just don't want to get my hopes up, only to be disappointed if we're not on the same page.

Can you provide a brief overview of the text?
<bot>: The BF and I are planning on marrying "someday". How do I find out what "someday" means to him without coming off as pushy?
