There is the possibility of a connection- unconsciously trying to connect with someone who reminds us of the father or a father figure in a way to make up for lost opportunities (whether it is seeking approval, attention, kindness, compliments, protection, etc) People also learn by example (social learning) If you have noticed a pattern, then there is always a connection.
One way to break this, is to look for patterns. The moment you realize that this is a person with similar traits to your father, try to figure out why you are involved with them in the first place. If you do not find any positive or comforting characteristics and if your intuition tells you that there is nothing substantial in the relationship, then reconsider it.
Another way to learn more about your self and possible subconscious drives is through counseling.
You're saying that you cannot help it. All behavior is driven by a purpose. You are engaging in something that you believe will make you happier and satisfied (even if in reality that is not the case) Also, behaviors can be corrected as long there is the awareness and the desire to do so.
It is possible to behave in a way that you're not fully aware of. That is natural to everyone.
