Relationship is failing

Been with my bf for 4.5 years. We haven’t been getting along too well lately. He said he is uncomfortable around me and has decided to move out of our apartment we share in February. He says he wants a reset from our patterns. However he doesn’t want to break up. This is all very confusing. He’s in his home state very far away for a month and I am in my hometown for another week or so. I’m giving him space but I honestly hardly hear from him. It’s Christmas eve and I haven’t heard from him all day. It’s like we haven’t been together for over 4 years. I get things have been difficult but...he just seems so in his head and is withdrawing. Meanwhile I’ve realized I still have a crush on an old friend. I would like to end things in person but he’s so far away. I feel guilty for still having feelings for this friend. Nothing terrible has gone down between my boyfriend and I. He just is so distant but seems like he just won’t end it himself. I don’t get it. I’m venting and would love your thoughts. Merry Christmas everyone. You’re all queens.
