The silence after my boyfriend left for a 3-month work trip is deafening

My boyfriend just left for a work assignment overseas, and it’s supposed to be three months. We live together, so the apartment feels way too quiet now. I tried keeping busy with my usual yoga classes and catching up with friends, but every evening around dinner time, I feel this sudden wave of loneliness that just hits hard. I've even started watching shows we used to watch together, but it’s not the same without him commenting or laughing beside me. I’m worried that this long stretch apart might change how we connect or make me feel more isolated than I want. I’m hoping to hear from anyone who’s been through a similar situation - did you find ways to keep the bond strong despite the distance? Also, how did you handle those moments when loneliness just felt overwhelming? What helped you feel closer even when you were miles apart?
