During an interview with Sam Mewis for ‘The Women's Game’ podcast, she said,“I would say Ben was huge in that support, and it’s so funny because it was like the start of our relationship. Rough! Rough timing for Ben. It was literally like the beginning of our relationship. I’m going through, like, the hardest time of my life. We were actually talking about that the other day, and we’re like, ‘Dang, that was rough.” I’m really happy we made it out of that.”She went on to add that Shelton put up with her ‘psychotic behaviours’, explaining,“He supported me so much, and obviously I was with him, supporting him while going through it, which I think was really good for me because I got to still be in the competitive environment. So it was just a good balance, and then he just gets it and understands me and dealt with my psychotic behaviors because I was just like this every day. I’m very happy that he was there for me.”On the tennis end of things, Ben Shelton was most recently seen in action at the Swiss Indoors. In Basel, the American made a second round exit in the singles event, while reaching the semifinals of the doubles event alongside India's Rohan Bopanna.
