<human>: As the title says, my boyfriend and I have been together for 3 years. We have talked marriage for a while and are both sure we want to marry each other, but there hasn't been any reason to rush.

Now, there kind of is. He has a very good shot of getting selected as a  military officer. His training would likely start next summer and last for 1-1.5 years. During this time, I will be finishing my second bachelor's in nursing. Should he get in, we have decided that we logically should get married before he leaves for training, for many reasons.

My question is, this is coming a lot sooner than we anticipated, and while we have talked a lot about our future together, I need to know what the most important topics we must discuss. Since we have lived together for 1.5 years, a lot of things (like entertaining, cleaning, house rules, etc) have already been worked out. However, I am wondering what other things we should talk about.

Should we combine finances? Pros/cons to this?

Prenup? (He is a lawyer so of course he thinks everyone should have a prenup, but neither of us have any investments/significant savings/inheritances to protect)

Other things to discuss? I would love to go to pre-marital counseling, but I am not sure we can afford it, and it is very hard to find non-religious counselors (we are both atheists). So, any insight/help would be appreciated!!

Can you condense the text into three sentences or less?
<bot>: Boyfriend and I may be getting married sooner than planned, help us make sure we have talked through all the important stuff!!
