<human>: Can you succinctly summarize the text in 1-3 sentences?

They have always had really bad fights to the point where they almost got a divorce but then that moment made everything better. My mom cheated on my dad early in their relationship more than once but they prevailed from that. 20 years later, my dad is depressed and tells me he doesn't think my mother loves him anymore.

My mom formed a complex from her bouts of cheating and has always thought my dad will cheat on her.

It makes me not believe in any form of happiness in marriage. Like no way can I believe in it. Like even if I do get married to my current bf, we will only end up being unhappily married with kids and cheating. I can't even imagine making such a mistake. This all is making me afraid of love and making me think twice about it.
<bot>: I may only be 19 but I'm ready to grow up now. I just don't want to make a mistake in any relationship I have. My parents seemingly unhappy marriage makes me feel this way.
