Summer married her husband because he offered her something Tom couldn't: certainty. When she meets Tom at the park bench on day 488, she explains that she married for the same reasons Tom believed in true love, because she finally felt certain. This reveals that Summer's skepticism about love wasn't about avoiding commitment entirely; she simply needed absolute certainty before marrying, which she didn't feel with Tom.

Foreshadowing: Summer's earlier comments about Tom's desire for certainty being unrealistic, combined with her deflecting questions about their future, hinted at her need for someone who could provide that certainty.

When Summer mentioned needing certainty, she meant she needed to be completely sure someone was right for her before committing to marriage.

This explains why she could marry someone else despite having genuine feelings for Tom.

Foreshadowing: Summer had always been skeptical about love and deflected questions about their future, indicating she was waiting for that level of certainty.
