To answer the title question, Yes I had difficulty in my relationship. I dated this guy for more than 4 years but the problem with him was that he was cheating on me, I never for once cheated on him. Every relationship have it's ups and downs,so I wasn't really bothered about him cheating on me,maybe because I felt it is in a men nature to cheat.
But the difficulty was him not been honest about his feeling with me.
Relationship is all about building yourselves to understanding.
