She's young and emotionally immature. And you're willfully not seeing a truckload of red flags that will show you what your future will be like if you rush into this.
If she's rushing things, do you think really you should view her with authority on how a relationship should be? I mean, that's great that her culture is different, you don't share her culture and if she's forcing it on you then do you think she values you for you? Or is it just about finding someone - anyone - for her? Is that what you want for yourself?
And her using living with you as emotional blackmail is pretty low. You didn't force her to move in with you. She chose to do it, and now she and her family want to tell you that you owe her something because of a choice that she made for herself?
Don't fall for this shit, dude. You talk in your post about what you did wrong. What about what SHE did wrong? She and her family want to confuse you and guilt you so you will look at her as a little girl whom you victimized, and by the tone of your post you seem to be falling for that storyline. In reality, she made her own choices for herself, and she's since shown her cards that she made the choice to live with you in order to obligate you into marrying her on her timeline. These are manipulative actions, are they not? Do you want to tie yourself to someone capable of manipulative actions?
Also, given that information, is this someone who loves you and whom you can trust? Perhaps, but you sure shouldn't decide that now, because you've only known her for a short time and I feel like her actions are selfish and shady. You need to gather a lot more evidence about who she really is and how she will treat you, and you need to do it with your eyes wide open so you don't miss any more red flags.
Also, you don't know who she REALLY is if you've known her for less than a year. How do you handle arguments? How will she be when the rush of the romance of a new relationship wears off? She's 23 years old, which means her freaking brain is still growing - she could turn into someone you don't recognize within the span of a just a few years.
You're a 34 year old man. Open your eyes and look around. What happens to men who marry 23 year old women who they've known for less than a year? A 95% chance of unhappiness. Sure, there are a few marriages that last, but they are very much in the minority. And how many of the few that last are happy? Even less.
Stick to your timeline so that you can be sure that this is someone worth marrying. If she leaves because you won't rush a huge life decision (one that is much riskier for males than for females), then you will have additional evidence that you were just a figurehead in her life plan. You'd know that your needs in marriage would be inconsequential, since it's always been about her. And you will thank your lucky stars you didn't put a ring on that.
