I think it's doable. 99% of our OOS students get residency. It just takes some sacrifices. For example, it might be better for your SO to travel to you instead of you going to him (or her) all the time. It didn't hinder my plans much--I made plans around the requirements. I think it would be silly to attend OSU and NOT get residency, since it cuts your tuition bill almost in half. I would say wait and see if you have a decision to make and then go from there
If OSU is the only school you get into, then you have a big decision to make. If you get into a school that fits more with your lifestyle, then that's another situation.
