<human>: Can you give me a shortened version of the text?

Basically I've been going out with this guy a month, thought he was pretty awesome etc. Was starting to really feel something. 
Last night we got into some deep talking. He said that he had a cynical view on a lot of things, especially love and relationships. Said there was a very high statistical chance that people don't find "the one" and don't spend the rest of their lives with someone. I know that this is true, but as someone who grew up with two parents who love each other, and with no divorce in my family at all, I have a very positive outlook on love (his parents had a nasty divorce). 

He also said that, even though he's never had a 6 year relationship, he believes that this is the maximum time you could realistically spend with another person, he said that around the 6 year mark you'd have found out all you need to know about the other person, and there's no real reason to continue a relationship at that point. As someone whos had a 4 and a half year relationship in the past, I feel the opposite and think that at 6 years you would only love the person more and want to spend even longer with them. 

I want to just put this down to the age difference. Am I just naive about relationships? Is it okay for him to feel this way? Should I take it to heart or no?
<bot>: bf doesn't believe in long term relationships or marriage, has cynical outlook, I'm the opposite but I feel naive about the subject.
