thats life and how we deal with it is what matters, you need to look a little more into you and find out why you are getting into turbulent relationships... it must be the type of person you are attracting or attracted to.
I've been doing alot of soul searching and have realised I have to open my mind a little as to who and how i date. Love never runs smoothly especially over years, it's work, but can be worth it, if you find that special someone that you can see a future with. Sometimes you have to look way beyond the instant attraction and not just be taken in by the moment!
