Misunderstandings cropped up frequently between you and past lovers, didn't they? It seemed as if you always ended up bewildered, apologizing for something when you didn't even know what you did wrong. Meanwhile, your lover pouted and sulked, wrapped in suspicion.
Much of the problem was in the fact that you didn't communicate very well. You were distanced from your emotions, burying yourself in work and your goals instead. And your lover imagined the worst of you, making up scenarios and then treating you as if you had erred somehow, or as if you'd made promises that you wouldn't keep.You are simply going to have to learn how to see eye-to-eye with someone else, and you won't do it by ignoring your problems. Gather your courage and start talking. Reveal your feelings. It's uncomfortable for you, but you must begin, since your partners tend to invent information to fill the gaps you leave. Though you don't know it, your ideal partner's feelings and desires are much the same as yours and a comfortable familiarity will fill your lives once you break through your block. Go for it -- warmth is a lot more fun than ice.
