Jake Gyllenhaal’s family wants him to marry Reese Witherspoon .

“They know she would be the perfect wife to settle down with,” a family friend told Us. “They all want Jake to get married soon and have kids with her.”

A source close to Jake’s sister, Maggie, agreed. “Maggie and the family love Reese. (She) is exactly what they want him to be with. They love that she has her own thing going on. She isn’t about being with Jake for any reason except she loves him.”

“Their closest friends think they will eventually marry. Reese just wants to make sure their lives make sense together before they do.” But the insider assured, “They keep saying ‘one day …’ and smiling. When the time is right, he will propose.”

“I wouldn’t be surprised if an engagement happens any day now but nobody finds out for months,” a pal of the über-private couple told Us.
