<human>: Can you condense the text into a few key points?

I've been with my girlfriend for about 2 years. I've known from the beginning that she wanted to be in law enforcement, as she comes from LEO family. I love her to no end, and I know I want to eventually marry her. We have awesome communication (except for this) and she's pretty much everything I could hope for in a partner. 

Recently we had a discussion with her uncle (who is also LEO) where he described how hard it is to maintain a happy family as a police officer, and he passive aggressively warned her that being a police officer will probably tear us apart. He said this because he knew I value family time very much and my career path is the opposite as hers. I asked her about this later and she didn't want  to talk about it because it was a non issue,claiming he's just projecting his own marital problems onto us and that we will make it work.

 I've recently been having doubts about proposing to this girl in a few months because of this. My research hasn't been encouraging either, as many posts say that LEO have terrible family lives (especially women because on top of the hours and stress, many men on the force will try to hook up with her if she's attractive--my girlfriend is very attractive by pretty much all standards). I trust her to not cheat, but other posts are describing its a main reason why women LEO marry other LEO. However are the hours/stress/surrounded by pretty much only men valid concerns, or are my feelings irrationally caused by the other blogs and her uncle?
<bot>: girlfriend is becoming LEO. I value family over everything especially in my future. Will her career choice eventually bring our relationship down (considering that many people say that LEO have terrible family lives)? thank you!
