Being in a long distance relationship is always seen as a difficult thing to deal with as a couple, but in my humble opinion, it really isn't; you just have to want to put in the effort to make it work. You can be 30 miles away, 300, or even 3,000, but nothing will ever work unless you and your partner put in the effort that is needed for the relationship to stay how it was when you were just 3 miles away!
I have been dating my wonderful boyfriend for two and a half years now, and being 312.1 miles away (yes I googled it) has definitely tested the waters, but we have learned so much about each other that we would not have if we had gone to the same school or even stayed home for college. For example, I never knew how much I love just being by myself. It brings so much peace and tranquility that I never knew I had. There is no denying that some days I wish we were together, but that is totally normal, and I have realized that being independent and away from him has made our relationship so much better in many ways I never thought it would.
A lot of the time there is a negative connotation with being in a long distance relationship. A lot of people just assume that things are not going to work out and that within the first few months you and your partner will break up because of it "being too hard". To put it quite simply, those are the people who take the easy way out! No one ever said long distance was easy! Think about it, in life failures happen when you (or someone else) do not put in the effort to make it successful. In a long distance relationship, you have to want to be there for you partner, but also grow into the person you are meant to become.
That being said, yes it is not ideal for you and your partner to go to different colleges, but the most important thing you both have to remember is that for the first time in your life YOU get to choose how life will pan out and YOU have to do what is best for yourself. Being in different places is the hardest thing, but knowing that you are both growing, is truthfully, one of the most amazing things you get to witness.
Nothing in life is ever easy, especially being away from someone you love for long periods of time! However, when you see each other being independent, growing into yourselves, and enjoying the journey, it makes the next time you see one another so much sweeter!!
