This can’t be judged well from afar imo.

My wife and i also got together two months before she was supposed to move to a different city. If people genuinely love each other, commuting and making things work is possible and people have done it before. In the case of my wife the different city didn’t work out after all. When we got together it started with us trying to talk ourselves out of it, because of all the reasons why it should not work. Now we are going strong since more than 5 years.

Life reality doesn’t work in terms of “now i will date and now i will find a suitable partner” or “now is not the time”. People who limit or push themselves like this end up sabotaging themselves imo.

You will have to trust your guts on this. It is set that you will move. If he is serious, he will find a solution for this. If he is that rich and he is unhappy where he lives now, there is no reason why he shouldn’t be able to make it work that you life in a different city. If he doesn’t, then it isn’t meant to be.

The age difference is an issue though in the sense that his life experience makes it easier for him to control situations and make promises not to hold up, than the other way round. This does not mean that it has to be the case. You should see to judge him by his actions, not by words.
