How soon did you fall in love

How soon did you guys know you were in love with your SO, hubby etc? I met a guy and I already feel like I’m in love with him. It’s been 4 months 😬 which i know yes is quick.. but i grew up knowing him. I never told him that i feel like i love him but I feel like it’s odd to say so soon but I honestly want to tell him. It’s nothing materialistic he does for me, it’s the small things he does. Like he doesn’t have a job yet and he constantly spends his last on me when he can, which I have a job i don’t make him do it he just does it, i am not big on material items AT ALL i can care less.. he also makes sure I’m safe when I’m going home, he loves going to church with me which is a PLUS bc I’m heavily into it, he waited for when I was ready to have sex and not force it on me. Like the small things he does really caught my attention.. he’s very sweet. One day we were listening to a song and it was talking about basically a women being spoiled and he goes “I can’t wait to get a job so I can spoil you” and my little heart melted 😭 I kind of had my doubts about this guy when he first messaged me bc I kind of grew up in the same apart complex as him when we were younger and growing up together he did have playerish ways but I seriously see the change in him. I didn’t want to take him serious at first and he didnt plan on being in a serious relationship which he had also told me but I can tell he has feelings for me. He admitted it once. You just know when someone is for you, I feel like he could be the one, but I always have that BUT feeling because I’ve had many heartbreaks.. I just already feel like I’m head over heels with him.. irdk it’s just a feeling I have.. but what if you know?
