I(w/o BPD, I can't seem to add a second flare) entered my first relationship this summer, it's with a wonderfully loving girl with BPD, I love her very much. After summer I moved to study a 6 hour train ride from her so we are currently doing a sort of long distance. We can't move together yet and we are still in the early period of our relationship.

Over time I have learnt a lot of her quirks as well as tried to understand her BPD. I've learnt how to handle her to a degree and I am able to take care of myself quite well in the process. Our relationship is getting more and more stable as time goes and we're starting to be able to deal with the long distance.

I love her a whole lot and if I could I would give her the entire world. I pay a lot of money to go see her twice a month, totalling about a 10 day period a month, I chat and talk to her throughout the day and I stay up late to talk to her and read her books to sleep over online voicechat(she can barely sleep unless I do). I am very happy and willing to do this, I love her after all. The issue is just that she seems to love me even more than that and so it feels as if my love is undervalued. 

She expresses(and I believe her 100%) that she would not know what to do without me, that she would harm/kill herself, I don't want to go into any more detail but the list goes on and on about what bad things would happen if I left her. I've helped her an immense amount, and I've according to her been an angel thats suddenly entered her completely fucked life. She's gotten a lot better since we met and so I can understand why she sees me in this light. She is very emotional (which is as far as I've understood very normal for those with BPD) and so her love for me is off the charts. Of course I appreciate this, it makes me feel incredibly loved and important, something I've never really experienced this way before. It's clear that she does her absolute best for me, despite the issues she has and I appreciate that a lot.

But at the same time I feel bad, it feels like my strong love is still *on* the charts, very high up but nevertheless still on it. It makes me feel like I'm not loving her enough, I wouldn't kill myself if she left me nor would my life be ruined completely. I am an emotional guy so I would be distraught yes, I would cry a lot, I wouldn't be able to function properly for a long while but nothing extreme like what she would go through and I feel bad. It feels like I'm not giving her the love she wants and deserves. She already questions my love a lot due to her disorder and because I'm quite bad at expressing such things (I've had to get better because of her)  and it's hard to deal with, it puts me in a tight spot and makes it feel like I what I'm doing for her and feeling for her is insufficient and theres nothing I can do about it. 

I'm cautious about telling her about this because it feels like she could take it the wrong way or too strongly, I don't want to hurt her. What should I do? Can I change my mindset on this?

Summary: I feel bad because I can't feel as strong emotions as my loved one. Need assistance on how to deal with the fact.
