Do you think failed relationships are hereditary?

Failed relationships are not hereditary, but they seem to be common. You are wise to wait for a relationship that will be the right one, and that will last. Even then, it will take hard work and dedication on the part of both of you to make it work. There are no magical formulas, only hard work. Love isn't something that "happens" to you so much as it is something that you DO. It involves seeking the very best FOR the other person more that what you can get from them. Of all the factors of a good relationship (love, feelings, companionship, compatibility, common interests, maturity level, etc.) YOU are the most important. It is YOU and your PARTNER, working together that determines the fate of your relationship. Good luck for a great future ahead, and God bless!
