econjew- good for you for your journey back to Torah and Hashem!
I am curious to understand better why you can’t be what you coin as yeshivish and still attend university?
You can maybe do a morning seder and then go to classes at night, or opposite. and if you look at going to university as a means to getting a parnassa to support a family IyH, that is what Hashem wants from you. And you can raise them teaching them that torah is the most important thing while still maitning a job. As long as you incorporate torah into your life (aka say brachos, learn torah, be a mentche, daven three times a day, spread ahava and truth etc.) I don’t see why going to university is stopping you from being frum!
