@ryleerayy2,
You have no idea if he's going out with other women. That's a conclusion you're jumping to.
Maybe he was in an accident. Maybe he violated parole. Maybe he was drafted. Maybe the spaceship from Planet Vuldur17 recalled him.
You have no way of knowing without at least attempting to contact him.
On his part (assuming the Vuldurians don't have him), he's probably wondering why you have lost interest, as you haven't tried to contact him.
Pick up the phone and call. At least then you'll know for sure, instead of polling random Internet strangers who may or may not be from Planet Vuldur17.
