First time advice seeker

First, I want to thank those who took the time to read my post because it is a bit long.

I've been dating a girl for a little over 2 months now. We had a great first date and all of the subsequent dates have been just as great as the first. We live about an hour away from each other but both of us have driven to see each other and have also shared paying for dinner when we go out to eat (me 75% her 25% approximately). We've spent the night at each others places both romantically and just to hang out. I've met a close friend of hers and she has met one of mine as well.

A week ago while I was at work she sent me the dreaded "we have to talk" message followed by the "how you deserve someone better than me". I met her at her place and she informed me of how her work has her traveling and that she wouldn't be able to see me for a month. She also told me of how her work has been weighing on her and she is looking for a different job and possibly move if the right job came along. She didn't want me to "wait for her" and thought I'd be sitting at home on the weekends while she was away. She also told me what happens if we don't work out? (I think she fears the month apart may make me lose interest in her.) I again told her we had something really good going on but I'd always be a friend to her if we didn't work out. (Not sure if I should have worded it like that.)

I explained to her that we both have lives outside of each other and that I'd see her when she got back. I told her we can't worry about what could happen in the future when the present between us is so great. I then told her we've never had the exclusivity talk (Which I don't know if I should have brought up at the time). It seemed to have calmed her down and she told me when she sent me that message she was just overwhelmed at work and panicked. We ended up spending the evening together taking a walk, going grocery shopping for her trip followed by cooking dinner together. I ended up sleeping over at her place. The next morning I asked for a personal possession of hers to keep with me to remind me of her while she was gone which she obliged to.

My questions are:
1. How should I handle the potential red flags that she threw at me?
2. We don't consider each other boyfriend/girlfriend yet the way we have acted around each other suggests so. Does this topic need to be breached when she comes back?

Thanks
