<human>: Give me a shortened version of the text

My girlfriend (21F) and I (25M) have been together for 5 years now. I'm very happy and know without a shadow of doubt that she's who I want to spend the rest of my life with. All that being said, her family knows nothing about me (aside from her older sister whom she's really close with) and it's starting to really affect our future together. She comes from a very religious conservative family, who quite frankly hates the idea of her being with someone outside her race (I'm black, she's Latina). They're very controlling and also believe that a woman should live with her parents until she's married off to her husband, which makes seeing her pass 10 PM impossible. She knows that her parents will disown her and keep her from seeing her younger siblings if she does go public with our relationship, so she's very conflicted about what to do. She's also told me that she's hesitant to come forward with our relationship because she feels guilty about the idea of dishonoring or ruining her family's reputation in their community, even if she knows she's not really doing anything wrong. 

I'm at a lost here. I'm just about to finish up with my Master's degree and want to take the next big steps in my life (buy a house, get married, have kids,etc.) but everytime I mention it she gets very upset and accuses me of giving her an ultimatum---of forcing her to choose between our relationship or her family. She'll often tell me that I did this to myself, since she told me what her situation was like way back when we first started dating (I'm her first and only boyfriend)... but I never intended to fall this much in love with her. She's been having really bad panic attacks about this lately, and I feel guilty about putting this much stress on her, but I don't know what much longer I can wait.

I know she loves me and I'm trying my best to be understanding about cultural differences, but is it really selfish of me to want this? I honestly don't know what to do. All I know is that I want to be with her. Any advice?
