Assalamu Alaikum
I do think that some families make it difficult for their children to get married, but at the same time there is no excuse for committing zina. A lot of guys and girls invest in haram relationships and do not want to get married because they don't feel they are "ready" whether it is due to completing education, age, or financial means, even when their parents are encouraging marriage. In essence, there are other activities and ways to spend your time more productively than to fall into Zina....like working and becoming financially stable, and taking the time to understand the deen, and actually utilizing your brain in figuring out the type of person you want to spend the rest of your life with. The guys who are very serious about marriage and are not getting their parents approval should realize that they don't really require their parents approval, and a girl whose father is refusing to marry her off if she is in desperate need to get married should also exercise her religious rights.
