<human>: It seems like every adult I talk to, married or not, always warns about "how marriage is so hard" or "everthing changes when you're married" and even "you're too young to understand". I may be a but naive, but am I actually incorrect in believing that marriage should be happy and simple? Of course, there will be arguments here and there, but isn't it still loving and comforting to know that you're married to your SO?

Half of my friends' parents are divorced, the others have parents that fight all the time, and the last few never mention their parents' marriage (which can be interpreted as a positive or a negative). Also, my parents marriage (25years) is definitely not one I'd aspire for, so maybe this is hindering my view on marriage?

I'm somewhat of a romantic and definitely an optimist, so it kind of saddens me to think that there's the possibility that all marriages are horrible. Of course, I'm not getting married anytime soon, but I haven't been able to get this off my mind.

Can you condense the text into three sentences or less?
<bot>: I'm always warned about the horrors/difficulties of marriage, yet is it really that bad? Personal experiences would be great.
