Lost my whole friend group

Lost my entire friend group after being friends for years. I moved during high school and while we gradually texted less, I stayed close with one friend. During my second year of college, I realized I was always the one reaching out - they never initiated contact with me anymore. When I did text, their responses were just surface-level. They blamed me for not making enough effort, but I was the only one trying to keep the friendships alive. Looking back, I can see the distance was growing before that, but it still hurts being made out to be the bad friend when I was the one putting in all the effort. Even though I know I deserve friends who actually want me around and make an effort too, the loneliness still hits hard sometimes. Anyone else deal with friend groups falling apart like this?
