A frum girl who is older (meaning close to or age thirty) is probably not looking for a learning boy, because ANY guy who is age appropriate to such a young woman and does not yet have a means of parnassah or plan for one because he is still in yeshivah f/t, will probably be perceived as not responsible marriage material. His f/t learning plan should already be far behind him (based on the boys who get married at 22 and learn for 3-5 years, which IMO is too long for f/t ANYTHING that does not result in earning a living, especially when one is married with children). At thirty or more a guy should be firmly establishing how he will support his family and even maybe have money put away at that point. THIS DOES NOT PRECLUDE HIS LEARNING EVERY DAY.
My son learns every night b’chavrusah and also on his own. He also went to school full time for his LMSW and is going back for his second Masters in Public Health, while holding down a 20-25 hour a week job. I am not saying this to boast about my son, so if I come off that way, it is unintentional. Lots of people have wonderful sons and daughters who are ambitious while at the same time deeply-committed to their Yiddishkeit and learning. I say it only to prove it can and should be done.
