in spanglish you don’t switch by word, you switch by phrase.
it’s not:
“[first part of the sentence in english], [second part of the sentence in english], mi amor.”
“[full english sentence], querida.”
it’s:
“[first part of the sentence in english], [segunda parte de la frase en español], mi amor.”

also miles is boricua, miguel is mexican. they have two different accents and use different vocabulary for certain words.
also miles is “nyourican” - a puerto rican native to new york - while his mom is directly from the island, so there are differences there, too, because his spanish is more influence by new york english. 
here’s some good references that aren’t google translate (which usually pulls from spain, a country that speaks vastly differently from latin america)
in spanish most words are gendered, so most feminine words end in a and masculine/gender neutral words end in o. adding ito/ita makes something cuter, smaller and more affectionate.
spanish nicknames that aren’t “mi amor”
“querido/a” - darling
“cariño” - dear (always masculine regardless, of who its being said to)
“mi princesa/príncipe” - my prince/princess
“mi rey/reina” - my king/queen
“papí/mamí” - can be used in any way; romantic, sexual, familial for one’s parent or child, or just platonically
“tesoro” - treasure
also spanish is a language that uses adjectives as terms of affection both cute ones and ones that might sound insensitive in english
and like most languages that are not english, spanish has multiple ways of saying i love you.
“te amo” - romantic
“te quiero” - familial, platonic (although there’s nothing wrong with using it romantically)
see also:
te adoro - i adore you
te deseo - i want you
te necesito - i need you
 and, of course, they can vary regionally too.
please use this because i have read a lot of really well written things that take me out of it because the use of spanglish is terrible. don’t just go on your presumptions that spanish/spanglish works in the same way that english does.
things that made me stop wanting to die that require no effort whatsoever

Almost all of these are about variety. Humans need stimulation! We need enrichment! We literally cannot do the same thing every day!
The other day I was feeling miserable, so I hopped on a bus and rode it all the way back to where I’d started, and my brain, which had finally had some proper stimulation via new environments, was suddenly ready to go again!
This is why taking walks/drives and trying new hobbies are good for you! Don’t turn yourself into a sad zoo animal! You need some pumpkins to roll around in your enclosure!
