yeah! i'd love to say they were secretive about it, especially if willow is the leader of the sentinels, i imagine they didn't want that getting out to the public. and tbh jac prefers keeping her private life private! perhaps there were rumors circling them but nothing confirmed?
perhaps they dated for about 2 years? and by that point, you kind of either say you're committed to the relationship or ya get out. jac could have dumped her if you want and it might have been a sudden rug-pulled-out type of thing, but i can see how jac struggles with long-term anything because of her experiences in foster care.
