WIBTA For not letting my exgf negotiate the breakup?

I (22m) broke it off with my gf (21f) a week ago. I regretted it immediately but I know I had to do it. I plan on moving home (2 states away) after we graduate while she plan on staying in our college town. She never expressed interests in moving to my town and long distance isnt an option for me (weve done it before and it caused us to break up and I generally am bad at texting). All this to say from my point of view we were bound to break up at the end of the school year, which made me emotionally pull away from her. I didnt say anything since I thought I could get over it but after Valentine’s day I knew I couldnt. I realized how much she loved me and saw a future with me and I couldnt stay with her knowing I didnt feel the same. When I broke it off she was begging for me to just stay for the rest of the year as well as saying she would move to my hometown for me. I sort of see where shes coming from but I think if we kept going until grad it would just delay the pain and the financial burden of moving to my hometown (its pretty expensive especially for a new grad) would be far too great and I wouldnt feel comfortable with her doing that for me, especially given I wouldnt do the same for her. However I feel like a huge asshole for doing this to her as I can tell shes not doing well. We are in no contact right now but Im rethinking everything. Should I have let her move for me? Should I have waited until grad?
