Need Your Feedback

Recently we bought a house and I'm not on the mortgage. I have student loans up to my ears and we aren't married- we decided it would be in both of our best interests to not have me consign. Besides, if we get married then we can revisit this topic at that point. 

So today at work, I'm minding my own business and all the other people in my office start telling me "don't get married", "marriage sucks", "you're too young to have kids and get married", "you need to go out and live your life." And then they told me about how he can kick me out of the house at any point in time and t was a dumb decision on my part. What the actual fuck? I'm 21. I never said ANYTHING to anyone about this topic and they all just roped me in to it. I'm pissed and irritated. Nobody is going to tell me how to live my life. Not all 21 year olds need to go out and party! And I do go out! But I got out with my boyfriend and we have a good time together! 

I hate people. 😡

Am I being ridiculous or would you be mad if people just started commenting on your relationship without knowing you or your significant other and telling you to leave them?
