Hello RP folks I've been lurking in here for quite some time now, amazed by the amount and quality of of the information here, and a bit hesitant to seek help with my issue which as you might have guessed is with a woman. So I'm hoping to get some external insight about what am I be doing wrong here.

To cut thing short, i [25M] am in a relationship with this woman [22F] and have been for 7 years thus far, it's been absolutely amazing, however without blabbering much, we have agreed from day one to get married when we have the means to do so, and I want nothing more in this world right now than to marry this girl, she on the other hand is giving me all sort of wrong vibes, wanting to delay said marriage for another two years, we both work decent jobs, and I already started saving towards this goal, and have asked her to assist me with a fraction of what I'm putting into this, and she refused and it got into a very heated argument, basically she's saying she would like to save up for a vehicle and also to help her parents, which I'm totally on board with, and have asked her to put only the minimum. Now it's not about the money as I can definitely save up for this solely, however I can't shake the feeling of me solely wanting this, and that I am the only one want this marriage as of now, even though it was something agreed upon much earlier in the relationship.

Basically she's saying she want to "achieve" some of her personal dreams before taking this marriage thing.

Now I can't help but to feel unwanted, and that I'm the only who wants this basically, I want this now more than ever, and I have been wanting it for more than for a while now, is it fair for to wait two year as she wants? Am I wrong for to feel extremely troubled by this.

I'm sorry for this random gibberish however I do need your insight on this.
