Being ” yeshivish” takes a lot of dedication. Kollel full time, black pants, white shirt. Speaking to women a bare minimum and university a no no. Kollel full time yes. No tv or secular radio.
Now, modern yeshivish is better to “label” yourself it sounds like.
This day and age you must have a parnosse and a heavy wallet at that. Kids, tuition, kosher food and its more expensive to live in a frum community in any big city.
My husband is “modern yeshivish” and doesn’t feel as a baal teshuvah that he needs to pretend to be “yeshivish”, he does not learn full time in a Kollel. You definetly need to choose a yeshivah( I suggest Ohr Somayach in eretz Yosrael or Shor Yoshuv in Far Rockaway and go either before you get married for at least one year or use your first year of marriage in a yeshiva in eretz yisrael. She should be willing to go to a sem while your in yeshiva so shes not lonley.
I know a yeshivish guy who is FFB, 35 and still not married. He says because he went pre med he was getting suggested women who were too “modern”. So, its a consequence to take.
