She recently had some nervousness about getting married and even returned her engagement ring, but now they are planning on following through with the wedding after an almost four year engagement.
A source said: "Jennifer started feeling like it just wasn't right. So many bad things have happened since they got engaged in 2008 that have prevented them from finally getting married, and she was worried that she was just trying too hard to make something happen that wasn't meant to be."
They tried to work on their issues, but Hudson had a rough time during William Balfour's murder trial, as he was found guilty of killing her mother, brother and nephew.
The source continued: "Jennifer and David quietly called off the wedding a few months ago and she even returned her ring to him. She was extremely stressed out and processing a lot of emotions about the murder of her family after the trial ended, and she just cracked."
After spending some time apart, Hudson changed her mind and they decided to get married after all.
The source added: "After things settled down, she realized that he was her rock and that she wanted to spend her life with him and keep building their family together. She is more sure than ever now that she is ready to get married."
The two are currently planning the wedding, but there haven't been any details revealed yet.
