Hello people, my gf (23) and me (21) have been together for a year now. This relationship has been bumpy here n there ever since we started dating (because of her bpd) but it seemed good for a while. Up until a couple of months earlier where I started seeing a sudden change. The focus is on her all the time and I end up giving more than I wish I'd receive back. 
Since a month she's been really stuck on the thought of marriage and everytime I try to tell her that I don't want to get married right now we end up fighting. She's my first girlfriend and I've honestly never really planned to get married in my life (have a lot of my own trauma to solve) but she never accepts my boundary. She starts bringing up stuff to make me feel bad and push myself into marrying her, e.g. her grandma that could die soon and she wouldn't see her only granddaughter getting married. I understand her side but mine doesn't get respected at all and it honestly scares me off and draws my love away out of protection for myself.
I'm really all over the place and would appreciate some uplifting words on what I can do..
