I have no issues saying, "I love you." To me, it's not that big of a deal. It's kind of a whatever thing for me, right? Because I have lots of love to share.
For my boyfriend and myself, it's more so in our actions. I took a 20 hour bus ride to meet him for the first time. I moved across the country with him (that was a 3 day drive). We share our food with each other (both of us hate sharing food) and it doesn't bother us. He always cooks for me (entirely accepting the fact I'm so lazy about it and honestly hate cooking). He will call me on the phone just to see how I'm doing (we live together, so it doesn't happen that often. But he's still like one of the only people to actually call lol).
Ya know, there's lots of little things and a few big things. But really, to me saying "I love you" doesn't actually mean all that much. It's all in the actions and the connections
