Past simple tense is formed by adding <u>-ed </u>(in some cases, -d or -ied) to the base form of the verb. The past simple tense of the verb "to splurge" is going to be <em>"splurged." </em>
Past progressive form, on the other hand, consists of <u>verb to be</u> and -<u>ING verb form</u> - "was splurging."
Past perfect form would be "had splurged", while past perfect progressive would be "had been splurging."
