Tznius – I think you really should check carefully if Touro will really be better than where you are now. It may be or it may be not – I wouldn’t know enough to be able to tell you. There are a lot of different programs and locations for Touro, and it seems that they are all very different.
Will there be more Frum girls there than where you are now? Are they the type of Frum girls whom it would be better for you to spend time with than the ones where you are now?
What are the goyim there like? Are they the type whom you will be less likely to spend time with? Some of the Touro branches are apparently full of non-American goyim. That may actually be an advantage, since you would be less likely to be influenced by them.
