Should I stop texting him?

Soo my ex and I broke up in March but still to this day we text. We tried working things out around October but it didn’t go too well. He recently had a crush on one of his girl best friends but I’m not sure whether or not he still likes her. We text pretty much all day everyday and I still have strong feelings. But in person we hardly talk. Should I stop texting him to move on or should I keep texting him to keep the connection just Incase something happens between us later on.
