The first sentence ("I'm not going to invite them...") is about the future—the speaker hasn't invited them yet but assumes they wouldn't come. The second sentence ("I didn’t invite them...") is about the past—the speaker already made the decision not to invite them, believing they wouldn’t have come.

The first is talking about what you will or won't do in the FUTURE. The second is talking about what you did or didn't do in the PAST.

Correction: What are the differences between these two sentences? 1. I’m not going to invite them to the party, they wouldn’t come anyway. Time: Now or future Meaning: I won’t invite them because I think they won’t come. 2. I didn’t invite them to the party, they wouldn’t have come anyway. Time: Past Meaning: I didn’t invite them because I think they wouldn’t have come.

The difference is in the time frame and the certainty implied: 1. "I'm not going to invite them to the party, they wouldn’t come anyway." * Future-focused – The speaker is talking about a decision not to invite them in the future. * "Wouldn't come" suggests the speaker is fairly certain they wouldn't attend even if invited. 2. "I didn't invite them to the party, they wouldn't have come anyway." * Past-focused – The speaker is talking about a decision already made (not inviting them). * "Wouldn't have come" reflects a hypothetical past situation — the speaker believes they wouldn't have attended even if invited. Summary: * Future decision → "I'm not going to invite them…" * Past decision → "I didn't invite them…"
