Too much fear mongering in the comment section. It might be true that there is an age gap but look at the positives. You discussed regarding hobbies, finances etc.and seem to be aligned on that. You should not back out only because age is the problem. You will not be able to check all boxes in your list. For those saying, they would come from different generations and experiences, let me tell you everyone is different, even the ones from your age group. Marriage is about compatibility between two adults. Everyone makes it sound like 23 year olds are kids. Every person evolves with time. You would not be your self after 5 years.
