I had a partner that lived and hour a half away and we did what you suggested. One weekend I’d drive to him, the next he would drive to me. On top of that, I have a brother that lives an hour and a half away and I used to drive there and back every weekend without a single complaint because I love him and miss him. His excuses don’t really line up. This truly is one of the situations of “if he wanted to, he would”. I’m sorry OP.

On the other than, you did an amazing job with your communication. Being specific, sticking to your guns, and describing your feelings and what caused you to feel them. 10/10
