Buddhist path X Romantic Relationships and Sons

First of all I will apologize because it will be hard to put that as a clear and simple question. Once a person decides to enter the Buddhist path, it becomes clear that one should avoid engaging in romantic relationships as impermanence will definitly create suffering for this person (either by changing or ending the relationship), also a relationship can reduce time for meditation and dhamma study. We can understand why monks are not married. Using the same logic a person should avoid having a child, as it will create strong attachments and dramaticaly reduce the time for other activities. That said, we still find lots of Buddhists that decide to have this "normal life", marriage, sons, career, etc... even though they practice the Buddha's teachings, meditate and understand anicca and emptiness. They believe in Samsara, rebirth and Nibbana, but they still make choices that will probably keep their minds tied to this plane. It must be a very hard moment in life, to decide what to do when there is a "conflict" like this. I'm facing such challenges in my life, because soon I will have to decide about marriage, sons etc. I will create strong bonds and attachments, anyone that passed thought the same thing could help?
