How ask the girl to be your girlfriend.?

[Brenda Fleming]

Pick a location that sets the right tone. It's important to pick a place where you can have enough privacy to ask your question. You can avoid any overly-romantic location, such as a candle-lit dinner, which will make your intentions too obvious and will make things more awkward if you are rejected. Asking during a long walk in a park or over quiet drinks can be just perfect.
Pick the right time. Evenings are more romantic and will allow the girl to focus on you, not her busy day. You can ask her on a weekend night, but be wary that this will make it look like a date already.
Make plans in advance. Be mysterious. Ask her to meet you a week in advance, so she'll be thinking about your intentions. This will show her that you're playful and thoughtful.

Have the right attitude. You should approach the evening with a positive attitude. Thinking that your conversation will go well can really help you succeed. If you have confidence in the future of your relationship, she will too.
