Should I text him?

I keep going back and forth on whether I should text a guy I went on some dates with about 6 months ago. I really liked him, but I let things fizzle out, as I was going through a family emergency at the time…. For some reason, he’s still kind of on my mind. I’m hesitant to text him because I know he’s likely seeing someone else now or (if he isn’t) probably isn’t interested at this point. But at the same time, at least texting him would maybe help me get him off my mind…
