Spanish is my first language and there is a lot of things wrong in this paragraph, I’m afraid.
It would be: “Maria MENSAJEA A Ovy en las redes sociales. Ovy invita a María a Venezuela. María LLAMA A Ovy cuando ella ESTÁ en Venezuela. Ovy invita a María a su casa. En la casa de Ovy, HAY MUCHA comida.”
I don’t know what you tried to say in the 7th sentence and after. Maybe change it to: “Maria me dijo, ‘Gracias,’ y comemos mucha comida. María bebe de los muchos diferentes tipos de jugos de fruta que tiene Ovy. Esa noche, María le dice a Ovy, “Te quiero(or ‘amo’ however, ‘amo’ is only when you really love someone and it sounds like a confession), Ovy.”
When Maria is describing Ovy it sounds ok. And the final sentence can be changed to “Te quiero también, María.” But you can use ‘amo’ if you really don’t want to change it.
Hope this helps.
