<human>: Condense the text into a few key points

Hello,

My girlfriend has been in a recently bad living situation for some time and has been searching for a new place to live. She found a place with 3 guys and seems excited to move in. Naturally, im not big on the idea, but finding a place to live is very hard in my city. 

I was trying to handle the situation well but while helping her move her things this weekend and meeting her roommates, i instinctively began to feel upset and fearful of the situation.

I want to be trusting and let it go but I know a living situation can have a big impact on all facets of your life, including relationships... I talked to her about the situation and she is upset that I am not trusting her.
<bot>: Are my feelings/fears justified or am I being too insecure/controlling? I would especially appreciate any similar shared experiences.
