The first thing is that it is 100% not for everyone. Being at college, I can see some couples constant struggles being apart and how it has drastically changed their relationship. I am happy to say that, for some reason unbeknownst to me, my relationship is just as amazing as it was when we were in high school. But that isn't always the case and there are things I've learned while being here that I hope can shed some insight on others going through the same thing.
The biggest struggle is always having to say goodbye. The thing I've noticed is that trust is the absolute make or break it in a long distance relationship. If there is no trust there is no relationship and, while this is true even if you live close to your significant other, it is especially prominent in a long distance relationship. There is no micromanaging someone else's life, knowing their every move, or being with them if they are into going out and partying every night.
I was unsure if I would be able to deal with having someone at home while I was away. Everyone was telling me I was going to be missing out on upcoming opportunities and "the college experience" and, for a while, I bought into all of that. I didn't know what to expect from college in the first place and then to have a boyfriend at home seemed so overwhelming for me.
Little did I know that, in the end, when it came down to it, I don't think of the missed opportunities at the school... because there aren't any. I am happy in my relationship and just because I chose to go away doesn't mean what we had all had to go away.
The biggest thing we've had to learn in this process is how to say goodbye without crying a whole river. The pain we both feel when we leave each other again validates that we are doing the right thing.
If it is meant to be there is a way and do not let anyone, especially people who don't know your relationship well, tell you that what you are doing is wrong. Do what is right for you in the end.
