Last debate had changed me

on Christmas Eve my partner surprised me with saying that they have been experiencing troubles with our relationship. Side note: Our anniversary is actually on Christmas because we made things official as apart of our gift for each other. I was worried that they didn’t have anything planned. Another thing to mention is that I’m a traveling nurse and they’re still finishing up med school so we only get to really be with each other during the holidays. So I was really excited about getting a surprise for our anniversary. Well the night before (Christmas Eve) he drops this news on me that he doesn’t know if we should continue our relationship because he doesn’t really enjoy long distance, he thinks he’s the reason why I didn’t take a promotion earlier this year so he’s holding me back, our set long distance time frame is too long, that he has been thinking that he hasn’t been doing enough so now he’s dug himself a hole and other things. This all was a huge surprise to me since he never informed me of these issues. After our convo he came back and kind of said “I think we can work on this”. Then after our Christmas celebration he said “I don’t really know if I want to break up anymore now that we’ve talked and I know I’m not holding you back.” I’m now at this point where I feel completely confused about where we are in this relationship. He randomly told me that we should work on our “physical sessions” and do them more often. I have a high libido so I’m fine with this but due to the whole “maybe we should break up” thing I just don’t know what to think or feel so im not really able to make my mind to think about intimacy. Can someone help me with figuring out what to do? Also he didn’t give me anything for our anniversary but he did take me to a show at our local theater. I just really don’t know what to feel or think.
