How do you know when you’re in love?

Seriously I don’t even know how to define it anymore. I’ve been married, thought I was in love with him (maybe I was?) but he ended up being such a huge jerk. I definitely still “love” my ex as a person but am confident I’m not in love with him.

I feel like my meaning of love really changed when I had my son. Like how could any romantic feelings ever compare to this? I’ll never love anyone as much as I love my son.

But I’m dating someone now and I feel like I might be in love with him but ??? I’ve confused myself with that word so many times I feel like I don’t really know what it means, and what being in love really feels like anymore.

I’m really asking, how do you know you’re in love with someone? And please don’t say “you just know” lol, because I’ve been through so much I think I will ALWAYS doubt it, I don’t think I’ll ever “just know” anymore.
