After she couldn't find the airport, Williams texted her and Yolanda has been trying to reach him. However, he's not responding to her texts or calls, even though it's the usual time they talk. She then tries reaching out to him on the same platform on which they met.

Watch the clip above to see how that goes and what she's concerned this means for their relationship.

Yolanda lost 150 pounds as part of her journey to achieve a healthier lifestyle following her husband's death.
