Say "yes" if you want to be his girlfriend. However, if you don't, tell him the truth and say "no." Never be hesitant to state the obvious. Never engage him in trivialities or amuse him in order to make him think you're also interested when, in fact, you're not. Also, remember that this is a serious relationship so be sure to keep this in mind while answering his questions.
If you already know what he does for a living, then it's easier to say yes. If you don't, then just ask him so you can find out before saying yes. It may help to think of it this way: Would you marry someone without knowing anything about them? Probably not. So why would you go out with someone who doesn't even give you a chance?
Finally, remember that this is a serious relationship so be sure to keep this in mind while answering his questions.
Asking him questions shows him that you are interested in him. This will make him feel important and loved. This is how relationships start - with questions and interest. So go ahead and ask him some questions - he'll love it!
If you really, really like him, you should tell him. Telling him how you feel, even if he has a girlfriend, might make you feel better. Gather your courage if you believe it is worthwhile to inform him. Face-to-face is the greatest method to tell him. However, with his girlfriend nearby, that may not always be the best option. You could also send him a text or an email.
In order for him to understand that you like him, first of all you need to like him yourself. If you do, then there is no need to say anything. He will know what kind of feeling you have for him by just looking at your face. If you don't like him, then saying so would be correct. Explain to him why you don't like him and let him know that you want him to stop liking her because she is already his girlfriend.
It is very important to tell him you like him if you truly feel this way. Otherwise, he won't know unless you say something. Even if he has a girlfriend, it is still possible for him to love you. So, if you don't tell him how you feel, he might never know.
When a guy wants you to be his girlfriend, he will make certain that you have no questions about his affections for you. He is forthright about what you mean to him and how much he loves your relationship, whether in person or by text. He shows you that he thinks you're beautiful and attractive, and doesn't hide his admiration for you. Most important, he demonstrates that he's willing to make sacrifices for you, like planning special dates or trips.
A guy who wants you to be his girlfriend will never ask you to be his friend first. He understands that relationships are more important than friendships, and he wants to be sure that you're ready to take things to the next level.
If you two get along well and there's an attraction between you, then he'll probably ask you out in person (not just through texts) so that there are no doubts about where he stands with you. If you don't feel comfortable meeting his family yet, he'll understand and wait until you're ready. Don't be afraid to tell him how you feel about his proposal -- if you don't want to be his girlfriend yet, then explain to him why and let him know what kind of changes you need to see from him before you can consider becoming more than friends.
Overall, being asked out as a girlfriend rather than a friend means that the guy is looking for a long-term commitment.
