New Year, New Hero by Susan Alison

Kate Benning and Tom Cole, both members of neighbourly households known locally as The Three Families, had always known they would marry each other.
However, Tom was stifling her, and Kate was determined to free herself of these marital expectations before the New Year began.
She dreamed of getting herself a new hero in the New Year.
And a dog. She'd always wanted a dog.
But nothing ever goes according to plan... From Goodreads.

This was weird and too far out. I know everything was connected in the end but it was confusing getting there. I like the MC in this story but the end was too mushy.
