<human>: Can you summarize the given text in a few sentences?

I'm 22, fiancé is 24, together for 2 years, live together for last 8 months, and will be getting married next summer. My parents are both 55.

Growing up, I was one of the few people I knew with still married parents. I have always wanted to get married and never really questioned if marriages could last or not. However, this changed about 2 years ago, shortly after my fiancé and I officially got together. My parents announced they were getting a divorce after being married for 20 years. I was not living at home anymore and this came as a pretty big shock, since while they had problems in the past I thought things were going well between them (they were taking vacations together, exercising, etc.)

Overall this hasn't affected my life in any major ways, I had a few cries about it early on and since then have been fine. BF has been great through everything too. I've felt like he was the one since about 6 months into our relationship, and I love him more than anything. I'm super excited to get married and spend our life together! Our few problems have been one time events, and handled successfully and maturely. I think we communicate really well.

I know I 100% want to be married with him, but sometimes I find myself questioning if you can ever REALLY know... Surely my parents thought they "knew", right? But 20 years later it all fell apart. I'm terrified that this could happen to us too. I feel like my parents getting divorced ripped away all the belief I had that marriages can last forever. His parents are still married, but it's still his dads second marriage :/

So my question is how can I keep my brain from thinking these stupid thoughts? We are also doing premarital counseling (yay license discount!) and I have brought this up a little bit, but not really discussed it too much yet since we've only been 2 times so far. We still have a couple weeks until our next appointment, so I would like any advice you guys have to work on this in the meantime.
<bot>: I'm an adult child of divorce who is now getting married. how do I stop worrying that all marriages are doomed to failure even when I know I want to get married, both to my fiancé and as a general life goal.
