OP, are you in the USA? Your spelling makes me think that you are, sorry if that's not the case. If so, a college aged child will be 18-22.
I've had two children go through the US college system very recently and things can be tough with them at that age, particularly if they attend a liberally thinking college. We were lucky that our views and politics align with our childrens', but we do know of people with conservative values who have really struggled with their offspring's differing views once they went to college. Plus, many US college age kids are very woke and accept no differing views from parents.
That being said, I don't think you can compare what you did at their age to what your daughter is doing now. Life has changed dramatically in the last 30 years and children are mainly not in the same place as we were at their age. The growing up and finding your place in the world seems to take longer, student debt is much higher and a more worrying prospect to pay off, housing costs more, the world is in a shit place, that's some of the things our children have to deal with. It also helps enormously to remember that brains are not finished maturing until about 25.
You and your wife do need to be on the same page, though, and should discuss in private what your hard limits are re house rules and behaviour, and stick to them. Your divorce has probably impacted your daughter more than you think and she may be thinking that it's just all going to fail spectacularly again.
