How do I know if it’s too early to say those three little words?

I realize that speaking those words aloud hold a lot of power and reactions can swing either way when your SO hears them but I still can’t help how I feel. I’ve loved only one person before my current bf but the entirety of the relationship (8 years off and on) was long distance/online and we only met in person earlier this year and he was nothing and everything that I’d expected but I quickly learned that “love” was never real when it came to him and probably wasn’t actually what I was feeling when we were together.

With my current boyfriend everything is absolutely incredible. I’m happier than I’ve ever been in my entire life and not a second goes by that I don’t think of him. He’s literally always on my mind lol. I find myself craving his presence when he’s away and when we’re together... I can’t even begin to describe how full my heart feels for him. We often just lay on our sides and gently caress the other’s cheek while gazing into each other’s eyes. He took care of me ALL day long when I was sick, not allowing me to move while he cleaned the room, cleaned up after my cat when he had an accident on the carpet, and even walked to the store to get me soup, crackers, and Gatorade so that I had some sort of food in my system. He’s also just recently surprised me with tickets to ComiCon. I know I love him but I don’t want to scare him by saying it too early but I can’t help the way I feel about him.
