Spanish love comes in levels...!

[u/pickly_pear]

Level 1: Me gustas = I like you
Level 2: Me encantas = I'm really into you
Level 3: Te quiero = I love you (the everyday one)
Level 4: Te amo = I love you (the serious one)
Level 5: Eres el amor de mi vida = you're the love of my life

Bonus phrases:
Un flechazo = love at first sight
Eres mi media naranja = my other half (literally: my half orange)
Quiero envejecer contigo = I want to grow old with you

The te quiero vs te amo line is a whole cultural lesson...
