Being attention starved is hard... [VENT]

So...

I feel like I'm in love with the boy I'm going out. He makes me happy and most important: he makes me comfortable in my own skin.

I feel incredibly attracted to him... Both romantically and sexually. I wanna be closer to him. I love when he hugs me, when he kisses me... I absolutely MELT whenever he shows affection towards me and I haven't felt like this in AGES.

I get butterflies in my stomach whenever we get to see each other, I keep smiling and it's just... So good.

But I'm scared to tell him how I feel... You see, while I'm so damn clingy and romantic at times, he's aromantic. So I'm terrified that this will push him away...
Yes, I told him that I like him very much yesterday and he replied with "I like you a lot too." and this was enough for my stupid brain to think "that's it, he loves you too."

Yage told me to tell him how I feel, my best friend told me to wait and tell him when it's time... But I don't know what to do. The last thing I want is to kill everything we had because I fell in love.

I'm terrified. I don't know what to do.
I wanna say "I love you" with all the letters while in his arms and laying in bed but I'm scared it'll be the last thing I tell him before he just... goes away from my life.

I hate this. I wish I was aro too.
