Can his nature be changed?

I think you must be very young and inexperienced. It is absolutely impossible to change your nature! The so-called need time to change is just an excuse. Maybe he likes you now, but he can never lack the excitement of new things. It can be said that this is the instinct of male animals, but some people have weak instincts, some people have strong instincts, and your boyfriend is the latter. What is instinct? It means sleepy and hungry. For him, it means dull and exciting. Do you think it is possible to change? You can only change it, so that you can tolerate his unfaithfulness-if you are lucky enough to find out. So think about it.
