GF compares her life to mine. Says I have it significantly easier. Is this toxic or am I being sensitive? Any advice? [32/M] [37/F]

Basically title.

She basically compares her life to mine and when she compares it, she always makes comments about how my life is easier.

Technically she isn’t wrong about it but she does diminish some aspects of it that makes me worried about the future.

I work a stable government job as an engineer. And make good money and I do not have to think about work outside of work. It’s great but I’ve been doing shift work and sometimes the days are long. I typically wake up at 4-5 am and get back home around 4 pm dead tired because traffic and just feeling like it’s a long day. Most days with commute and getting ready it’s 12 hrs 5 days a week. I get 7 hours of sleep typically. I’m generally not stressed but just physically tired.

I also changed my shift because she wanted me to be on first shift and not 2nd shift. I deal with significantly less traffic on 2nd shift.

My current commute is 19 miles and if I drive to her place it ends up being 37 miles one way. She wants me to move closer to her which will make my commute miserable and that I have to do it every day.

She makes small comments about how she has it harder than I do. She does work significantly longer than I do and she has a lot harder projects than I do. She does get to work from home most of the time.

But it also feels like my job does not matter. The stuff that I do doesn’t matter. I never feel supported. Something happens at work, I have to resolve it internally while I listen to her rant about her job or her coworkers.

There’s other aspects but I’m generally not sure how to feel. If I’m being immature about this or if I’m right on this.

I don’t talk about my work or ever really feel supported when I bring up anything. She’s very much career oriented and it’s been her whole life. But because she’s so busy at work, I never talk about my work (because it’s so low level and it doesn’t matter). Or I don’t talk about my hobbies because she doesn’t have the time to even have hobbies of her own. I drive 7 days a week because she doesn’t want to stay in doors on weekends. I pay for like 90% of stuff. And I starting to genuinely question why I’m doing this stuff.

I don’t know how to approach this. Is this toxic or am I just being immature?

TLDR; I feel like I’m not sure if this is toxic if there’s some truth to what she is saying. But either way, it makes me feel like shit. But she doesn’t know I feel so unsupported and she’s too selfish or I’m too immature. Makes me question why I changed shifts or even am considering the miserable commute five days a week.
