I think that every child who has had a rough relationship with a parent seeks the closure when they are adults. My boyfriend has many bad habits and little ticks that causes a reaction out of him which is not always pleasant but its all due to his childhood. He has had many inconsistency and he had to face things on his own and he finds comfort in not being responsible for anybody but himself, We were madly inlove and we were the perfect couple and he was always the one to progress and take the steps in our relationship so he wanted us to get this serious but he couldnt handle the responsibility of taking care of me in all aspects of our life living together. Things became routine and monotonous and we stopped being the young ambitious people we use to be. He lost his drive and the spark and became depressed  after his loss and it caused troubles in our relationship where i was overworked and resentful. We argued alot more than normal and he eventually just wanted to be single and there was nothing i could do to change his mind.
