My girlfriend complains about everything and I’m sick to death of hearing it

Hi,

So my girlfriend and I have been together for 2 years now, she’s at UNI and works a small part time job and I work full time and I’m also studying to become an electrician outside of work.
We are both busy but never fail to make time for eachother, we spend a lot of time together, wether it’s on FaceTime or in person, but I’m starting to dread talking to her or spend time with her which sounds really bad because I love her to bits but it’s getting bad…

She complains about EVERYTHING! But it’s not like a small conversation we have that’s over in 20 minutes, it goes on for hours and i mean hours…
She will complain about UNI, work, family, money, weather, her health and the list goes on.
I’m not saying she can’t complain about something that’s hurting her but she takes it to another level…

Every single day for the past year now if I had to guess, she had told me she feels nauseous or tired, Ofcourse I care for her and I listen to her and try help her out but it never seems to be enough. She’s been to the doctors and they told her everything is fine.

Regarding everything else she complains about, I don’t even know what to say anymore, I’ve sat there and listened for hours on end every single day and it’s exhausted me, I don’t even know what to say to her anymore apart from :

“yeah I can see why that upsets you” OR “yeah I understand, you must be mad” OR “i know what you mean” etc…
I’ve basically rinsed every single possible reply of validating her feelings. I even challenge her where necessary (which never works out because she pulls the “do you even love me” card and convinces herself I’m not there for her anymore)

I don’t know what to say or what to do, it’s bringing down my mental health and I feel like I’m walking on egg shells with her because whenever I also have something on my mind she turns it into a competition about who’s problems are worse so now I feel like I can’t even turn to her when I need to talk about something.

She used to be impulsive with her money and would buy a coffee and a pastry from the store every day and it adds up over time, she complains so much about how guilty she feels for wasting her money I don’t even know what to say to her anymore. If the weather is too hot or cold she will literally book an uber for a 5 minute walk to the store then complain she’s running out of money.

She also never listens to my problems either when on the off chance I talk about something on my mind, she says she doesn’t understand and says she doesn’t know what to say then ignores me. She somehow turns my feelings into a debate, it feels like I’m in a police station being interrogated and I have to try prove to her why I feel what I feel!!!

I’ve spoke to her about this and she just cries and cries then asks if I even love her!!???

I could go on forever about this with so many more examples but it would become too long to read, this one is quite long sorry.

***TLDR****

My girlfriend complains about everything and it’s exhausting, whenever I complain she turns it into a debate and interrogates me or turns it into a competition about who’s problems are worse or just ignores me and refuses to listen because she doesn’t know what to say.
