Got Dumped by My Girlfriend

My girlfriend of 2 months dumped me. I know my situation is nothing comparing the posts in this subreddit but I really feel at an end. She lives 500km away from me and we could communicate so less because of her conservative mother. I could only see her once and felt like she is the love of my life. 2 days ago she told me she can not concentrate on her studies and exams because of thinking me (she noted it's not in a bad way but in a good way). I really couldn't find any solution but waiting 6 months for her semester and school to be over so she could move into my city or anywhere where her mother wouldn't be a problem anymore. And today I woken up with a text she can not wait 6 months and does not want me to wait anymore just because things might change in the manner of time. I really feel shaken up and feelingless. I dreamt of her so naively, patiently waited for her all the time and felt everything was pure and all that. I really thought I found the one. And this is also second time this exact situation happens in 6 months. Am I the one who overthinks and exaggerates the relationship I'm in? Thanks a lot for your helps beforehand.
