"Busy day tomorrow," Evan, 38, captioned a photo of his Friday, July 9, calendar.
Evan marked "Tyler Andrew's 39th birthday" on Friday and revealed a 12PM therapy session.
Evan then wrote, "Vasectomy appointment for real this time" at 3PM.
The Season 3 Bachelor in Paradise alum proceeded to joke in the 4PM-5PM timeslots, "Ask me anything Valium edition. Release OnlyFans livestream of snip for only 6 low payments of 59.99 plus shipping and handling."
At 6PM, the erectile dysfunction specialist added, "Evan out until 2026."
Evan has three sons -- Ensley, Nathan and Liam -- from his first marriage.
After competing for JoJo Fletcher on Season 12 of The Bachelorette in 2016, Evan went on to search for love on Bachelor in Paradise's third season that same year and fell hard and fast for Carly, 35.
Evan and Carly got engaged during the Bachelor in Paradise September 2016 finale and tied the knot in June 2017. Carly then gave birth to their daughter, Bella, 3, and son, Charlie, 19 months.
Jade added of Carly, "So, I don't know. I think she's happy where she is right now, and I think she's just kind of trying to figure out what's best for their family."
Carly admitted in late December she was "very sad" after her breakup with Evan and going through a divorce "just sucks." She said, however, "all wounds heal" with time.
Evan didn't break his silence about the split until April 2021, when he called himself "an easy target" for criticism and gossip since he had chosen to be quiet about the separation.
Evan said in June that he is "happy" and "dating" again, but now it appears he may be interested in working things out with Carly.
When Carly and Evan met in Mexico on Bachelor in Paradise, Evan pursued Carly with determination only to face resistance in the beginning of the season, but Carly slowly fell in love with his quirks and personality.
