Well to me at least, there's nothing wrong with going to university for the sake of pursuing a career-benefitting degree. Hell, I know middle-aged people who did that! BUT his intentions aren't that, but rather to "meet people and have fun." That's already a red flag. He needs to grow the hell up. There are other ways of meeting people, especially since he's 30 already. Besides, I don't trust him to stay loyal.

Its okay to back off whenever you want. I totally get you. You aren't getting any younger (and we all know that most women can't have kids at the age of +50). So yeah. You have a right to back off. and he has the right to go to uni and have fun.
