When did you know you loved your significant other?

He's my ex of 4-5ish years, I was just texting him about some issue I had with my mum. He pretty abruptly ended the conversation without really bothering to reply to what I had said as he was about to hang out with his friends. I felt a bit hurt, but whatever it wasn't a huge deal as I knew he had plans. Anyway so later that evening, he calls me (which I hadn't expected as he was staying the night with his friend) and asks me to finish what I was saying. At that point I was already over my issue, I just really felt in that moment that he cared what I had to say, how I felt, wanted to talk to me and help if at all possible...

Typing this out, it seems super insignificant and like I have pretty low standards. Whatever. This is when I knew. And it felt great to matter to someone. God that sounds sad. You know what I mean.
