Hi everyone. So about three weeks ago I was offered an assistantship at a school, and was told I would need to let them know within a few days if I would be taking the position and attending their school. They really emphasized that it was important to let them know asap since they need to fill the positions. Two days later, I told them through email that I would be accepting the position and attending their school. I wasn't ecstatic about attending there, but I figured it was such a great value and I couldn't pass it up. I sent in my deposit as well but it is refundable until April 15th.
So fast forward to now, I attended an open house at a school I didn't think I would like, but I ended up falling in love with it. I have decided that I will absolutely be attending this school and I sent in my deposit. I was wondering how I should approach the school I already committed to verbally, but now am not attending. Should I be honest and say I liked another school better? Should I be extremely apologetic and just say something vague like "another opportunity presented itself and I feel that I need to take it?" I feel guilty, but I also know this is something I need to do. I would love to hear other's opinions... Thank you
