I (28M) feel like my long-distance girlfriend (26F), whom I've been with for three years, doesn't understand my perspective.

Here’s a rewritten version of your text: I want to provide a little background about my situation. I’m a single father of a child with special needs, living in a small city while my girlfriend resides about two hours away in a larger city across state lines. Throughout our relationship, we’ve engaged in various discussions about our future together, including the possibility of marriage and our thoughts on having children. We share many values, such as our desire for kids and our love languages. However, when it comes to the topic of where we would live if we got married, I’ve mentioned to her that, given her job as a bank teller, I would like her to consider moving with me. I have a well-paying job here and, since my son requires specialized support, I want him to continue at his current school, which has an excellent staff. She, on the other hand, expresses that there are no job opportunities with her bank in my city and that she isn’t interested in working for any other bank. I acknowledge that it may seem selfish for me to ask her to move instead of relocating myself, but I believe it would be simpler for her to join me post-marriage due to the licensing requirements for my job, which can involve lengthy processes in different states. She often becomes upset by this suggestion, feeling that there are more opportunities in her city, that she enjoys her current job, and that my motivation for wanting her to move is convenience. We’ve also discussed our hopes for having children. My girlfriend hasn’t menstruated for several years, and I’ve urged her to seek medical advice, worried about possible underlying issues. While she has mentioned she’d go, she often brushes it off, citing her previous doctor’s departure as a barrier and suggesting she thinks she has PCOS, although her doctor previously told her otherwise. I’ve provided her with recommendations for medical professionals, emphasizing the importance of understanding her health in relation to our future family plans, but she tends to dismiss my concerns, saying we can address it once we’re married and ready for kids. Lately, I’ve been questioning whether I’m being selfish or overthinking things. I love my girlfriend and have considered marrying her, but I worry that she may not be ready for that commitment despite her frequent discussions about it. I’m at a crossroads, uncertain if I should end the relationship to avoid wasting either of our time, or if I’m acting too hastily.
