<human>: Could you distill the essence of the text into 1-3 sentences?

A little background: I'm a full-time med student and I work full-time in an office to put myself through graduate school. I can pay for rent and all my other expenses by myself, but I don't have a lot of disposable income after the bills are paid for.

My boyfriend and I have been seeing each other for about 5 months and he's nothing but amazing to me. We have so much in common, he makes me happy, and I can't imagine a life without him. The only issue is that I can't afford to be going out all the time. Before we started dating, I was perfectly fine staying in during the weekend and studying or reading books (mostly because it saved me money). But now, I've been breaking my wallet constantly and barely affording rent every month. It's not that he mooches off of me, we often split the bill or take turns paying. He's already graduated and established with his own house and car while I'm still building myself up, and it's quite discouraging. He enjoys the night life and I just can't afford it all the time. I don't know how to bring it up, it's embarassing to me. He doesn't know how much I make and isn't aware of my stuggle. How do I bring something like this to his attention without looking like a broke loser?
<bot>: I'm dating somebody who's at a different point in life as I, and treats it as if we're on the same wavelength. I don't know how to address it.
