Dating Sue Ellen LaRocca

Trent Olsen is dating Sue Ellen LaRocca. They first started talking on March 16, 2021, and soon started dating.


One year ago today I started chatting with this incredible woman. After weeks of talking and flirting, I quickly realized this was an individual I couldn’t imagine not being in my life. Feelings grew stronger, and although we lived in different states, we decided there was no reason not to date long distance. After a few visits to each other, it became obvious I was head over heels for her.

We made it official and then the pandemic worsened. I couldn’t imagine more of a trial than physical distance and social restrictions. It tested all aspects of our relationship from trust to communication. As many people currently wish they could get the last year back, I wouldn’t trade it for anything because I found my person amidst the process. I love you @sueboo87. Happy one year and to all the future celebrations. Thank you for always having my back and stealing my heart. #myperson #mypartner #mylaroux

As of now, the pair have been together for two years.
