Followed my gf to her college

I will be a junior in college next semester. 
I essentially picked the school because my two year gf who will be a freshman chose to go there. She will be there one semester before I arrive in the spring
She is in two clubs I would be interested in, however I am afraid if something goes wrong between us that it will be very uncomfortable for me to remain in them.
I know I screwed up by following her to the school but I didn’t think I would want to be in a long distance relationship any longer and I didnt want to seperate from her.
I’m going to join a third one that’s a sport I enjoy to have my own club.
I dont want to be apart of her immediate friends however I will know no one when I arrive so I might not have a choice for awhile.
Do you think I should switch schools next semester or just go through it and see what happens?
Should I let the possibility of us seperating affect my choices in club anyways? I dont see us seperating but you never know.
I regret letting my emotions get in the way of logic but the school I would of gone to was not much better than the one she was at so thats how I rationalized it.
Do you guys think I set up the possibilty to screw myself?
Whats the best way I can handle myself moving forward?

We also have one class together for next semester. She sees no problem in us taking a course and being in the same clubs. However I see a possible recipe for a very uncomfortable situation if things go south.
Should I at the very least also switch out of that course for a different time slot?
Any help is greatly appreciated, I went to a bad college my first two years and she was someone who kept me comapny throughout it even though we were still in a long distance relationship. I just want to do college right this time and have a decent experience while I still can.

Please someone take the time to offer me an advice on the best way you think I can move forward

You chose this college for your own reasons separate from your girlfriend’s choice. You definitely do not need to take the same class that she’s taking during the same semester. You also do not have to join the same two clubs. You seem worried about the issue, so you can easily adjust your class schedule, choose different ECs, and then see what happens when you continue dating.

This are not destined to go south, but they are very likely too if there isn’t enough personal space. Be friendly with your lovers friends don’t be true friends. There are too many people, hobbies, and pass times in this world to become too entwined in another person. Particularly before you both have actually settled down with one another. Even the best couples in the world need their alone time.

I would actually agree with here that sharing a class is hardly a big deal. Semesters are only about a dozen weeks and one class is not a lot of time together. I would, however, keep ECs separate. If its a big volunteering club, then that is something that shouldn’t be an issues, but if it is more of a friend/hobby club, then I would recommend sticking to separate ones.
