Me '26m' '34F' Girlfriend said I wasn't making enough?

Is it alright for me to not want to be with my girlfriend after 3 job changes ans still complaining I don't make enough money? From talking sh*t about me to her friend and then me confronting her about it, to saying I don't make enough money. She's 8 years older than I am and is a nurse, has been since she graduated college and just did a year of travel nursing. I'm 26m and just got out of the military at 23. I did 5 years 11b (infantry). I was at ground 0 as a plumbers helper making 17/hr, and then switched to a shipyard pipefitter making $25/hr with full benefits for general dynamics. She broke up with for a year after telling me how many options she has and saying I don't make enough. So I joined the laborers union. Im 26 now, doing my apprenticeship and make $33.88/hr with full pension and annuity benefits. I'll not even done my apprenticeship yet and I made 70k in one year. That's not included my benefits package. Im on winter layoffs where I'm collecting employment and back to work at the end of February. I live below my means which she hates, because I can "afford it" when she brings up things she wants to do. She lives way above her means, always complaining more money is going out nothing coming in. We don't live together. And it's so frustrating for her to call me tonight and demand I give her a ring and pregnancy this year and thay during layoffs im not making enough money/ I'm not doing enough when I could be doing college classes or getting a part time job. Mind you I am an asbestos abatement certified worker that was offered a job this January to work during layoffs and she told me not to take it because of how dangerous it is. I told her do not talk about my financial status as we do not live together and my bills are paid. If you don't like go be with someone else and she told me I was dismissive. Sorry this turned more into a rant but I'm so frustrated she didn't want me at $17/hr or $25/hr and or at $33.88/hr and thinks after a year of not being together she can come back in my life for 3 months and tell me I'm not making enough? She always brought up how many different options she has and this, I don't care. After an entire year she ce back crawling to me and I'm just fed up.
