Should I give him an ultimatum?

Anonymous
I've been dating this guy for three months now and I know for sure that he is seeing/having sex with other people. I'm not cool with this behavior, so do I give him an ultimatum or walk away? In the past I would have walked as soon as I found out that he was having sex with other people but I really like this guy so I'm having a difficult time deciding what to do. I don't want to get my heart broken but I also don't want to waste my time if we aren't going anywhere. I know he cares about me but is that enough? So folks, should I give this man an ultimatum and tell him that if he doesn't choose to be monogamous he'll loose me, or do I wait it out and see how things play out in the next few weeks?
