Catching feelings for my friends with benefits?

So I’ve been sleeping with someone for 3.5 years and like I’ve told him I had feelings before and we semi dated and it kinda faded out. sometimes we do cute things together like drink wine & watch the sunset but most of the time we don’t really talk between hanging out & then I feel kinda bummed after. Why would someone keep a girl around for so long, just
for the sex & convenience? Am I just playing myself I feel like there’s plenty of other people out there
