snap judgement

Snap Map emotionally devastates me. My significant other and I split up (amicably) not long ago because he said he needed to be alone and "focus on himself". We agreed we'd remain friends. Once social distancing started his Snapchat location showed him at a woman's house, for four days straight. They met right before he and I split so now I'm wondering? I finally asked about catching up a few days ago and he replied that he had just left town. Our university permanently canceled classes that evening. I will probably never see him again. I can't tell if I'm more hurt by the possibility that he left me for someone he met a week before we split, or if I'm more hurt that he's made no effort to keep in touch like we said we would. I think the keeping in touch.
