Hi Reddit, I'm quite new here but anyway here's my story(English is not my first language but I'll do my best)  :

As you read in the title, she is 27 and I am 19. While it may seem like a big gap, we have already been dating for 1 year and 7 months and it seemed like living in paradise. 

Even though I am younger I have somehow always been a bit more mature than my age since I was thrown out earlier in the "adult world" thanks to my sport and few other things. 

But let's come to where the problem lies : since one month ago, she starts to question our relationship and its future. She stresses the fact she loves me deeply but she seems to bend over the social pressure of her friends getting married, buying their flats, etc... 

As a result she is afraid she might be single and unmarried at ~35 because I am too young to have a settled life, even though she knows I am likely to be accepted in one of the 5 best business school of the country next year. Therefore, it looks like she wants to break up. 
She brings the subject every so and then and I just can't find the right words to comfort her... I know she loves me but I feel like she may break up anyway. 

I am so lost, she is my everything and I really don't want to lose her. Please help me.
