Since you’re both 25 years old and have been dating seven months, it’s now fair to ask about his girlfriend, and if he’s still committed to her. Since the relationship started with him disclosing to you that he has a girlfriend, which was his way of letting you know you shouldn’t expect a commitment from him, and he seems to be interested in you beyond just casual dating, this is definitely the time to find out about monogamy. If he’s still with her, then expect more of the same. If he isn’t, then there’s a better chance that he’s feeling loyal to you.
Overall, the best thing you can do is to get out of the intra-personal wishful thinking and to get into the interpersonal business of relationships! What goes on between you and you is thinking. What goes on between you and him is your relationship. 😉 Six months into dating is usually when you decide whether or not you both want to be monogamous and if he doesn’t, then you get to decide whether or not you want to stay in the game. But if you don’t ask, which at this point in time is fair, you won’t know. 😉
