Have you ever been heartbroken or burnt out?

I've been single for so long that I've stopped trying to get to know people in that way. Like I've had people show interest, a few girls at work told me they think I'm cute. I just said thank you and kept doing my work. Even tho I like one of them I'm just not to thrilled or interest about pursuing a non professional relationship even tho for the longest time that's all I've wanted I feel like my fire is gone.
