<human>: My SO (18M) of four months and I (19F) had an argument yesterday because I thought he'd lied to me. It became a really big deal because I thought he'd gotten drunk with mates when he'd told me he'd only had one drink, but it turned out he'd only thrown up because of food poisoning and I was completely mistaken... 

Anyway, although it all turned out to be just miscommunication, I couldn't help wondering what happens when your trust in your SO has been broken. I mean, really broken. I've had other long-term relationships, but I'm aware of my own youth and I've never really had a SO go behind my back or anything to that effect in a relationship before.

I'm aware that over the course of relationships, many things are tested and have to be compromised, but I wanted to ask whether you have known trust, once broken, to ever be reformed? Or is that just something in a relationship that you simply can't lose?

Give me the gist of the text in a nutshell
<bot>: An argument I had yesterday got me wondering, if your trust is broken in a relationship, do you think it can ever be what it was again?
