There are two separate issues here. Making a wedding/getting married.
When you find the right person you do not put off getting married. However, making a wedding is a choice. I remember, in my generation, 40 years ago, several of my friends got married without a wedding – with a rav, family & a minyan. Then her friends & family made “extra special” sheva brachot for the couple.
I know it is hard, but just ignore social pressures.
I second this. There is no need to not get married; one can then pitch a tent in Lakewood’s Tent City and search for roots in the swamp instead of relying on others.
