Explanation:
We can translate the sentence hace dos meses que vivo en Texas into I've lived in Texas for two months. So the group of words hace dos meses comes from a common formula in Spanish:
Hace + number + días/meses/años
This is used to tell you something happens from the past until now. If the number is uno (one), días/meses/años (plural form) changes to día/mes/año (singular form)
