I Told Him I Love Him

He already texted me once the other night saying "I love you" when he was going to bed. I didn't respond to that one because by the time I thought about it long enough, I didn't want to text him and run the risk of waking him up.
Over the past few days, I've been thinking about it. After he kissed me today, I thought about it a lot. And I think I do love him.
Well tonight he texted me saying he was going to bed. At the end it said "I love you " I had to respond quickly, but I didn't know exactly what to say. But I ended up saying "I love you too , good night"
So now I've told him I love him. I think it's true. It makes me feel good to say it and think it and think about him. I just can't be 100% positive that it's love because I don't have anything to compare it too. He does.
I really think though that I love him, or that I'm falling in love with him and will love him very soon. I think I did, maybe not the "right thing", but at least an ok thing, I hope so!
I'm freaking out about this a little, but not in the bad way. More excited. I keep saying "oh my god, oh my god, I told him I love him!" like excited, but still maybe I little nervous. I don't want to tell him something that's not true, I don't want to lie. I don't think I am. But, yeah, freaking out a little, not a lot.
