It sounds like you have competition! He has a crush on another woman, and you have a head’s up that he’s got a romantic interest elsewhere. If you set up an ultimatum or try to control him, you’ll lose him. Instead, accept the competition, and be the girlfriend who wins him over. 😎 I know that you’re upset about this, and even angry, but you have to take an outlook that gets you what you want — not loses it for you. Whenever you competition, turn up your A game instead of trying to control someone you shouldn’t be controlling. You’ve been dating for a year now and competition is a part of dating and of life. Embrace it and play to win. 🙂
