For bros who have difficulty picking up ladies, don't set your expectation for a very pretty,sexy, lady. For starter, is better to chat with as many ladies as possible who at least have a decent/cute look that catches your attention. Think of a special line, don't do the usual "hello, hi, hey pretty, lets chat" etc.
When she has added you, this means you must have did the 'right' thing to catch her immediate attention. Make sure the conversation is enjoyable, topics that generate her interest, if you have a sense of humor is even better. Find out what is her interest?
How do you know whether she is interested with you further? Easy. If she is responsive to your conversation in the next few days, that's great, she enjoy talking to you or like your attention. If she is not responsive is all right, everyone is busy working, be chill and msg her later after work to chat again. Occassionally test water a bit to see whether she can accept cheeky comment. If she flirts back or reply back cheeky as well, is amber light and may be turn green. If she flirting with you directly, is green light and move on to ask her out. If she response shyly, gradually raise the bar and see how she reacts accordingly.
If she always reply late, reply only with one to three words to your question, i usually won't follow up because i know i am not her type or she is too busy with life, if you wish to remain presistent am not stopping you. Patience is a virtue too.
If your are still chatting actively after a week. Is time to invite her out for coffee or a meal.
Let's state an actual example.
Today i chatted with a new lady added me on app. Did the usual self intro. Told me her age and status, i made a humor that got her laughing. She started to tell me a bit more of herself and reveal something deeper, somethin forbidden if your know what i mean, which is quite direct and open of her. Then the convo stop after my last qun. Later she msg me to explain she was busy, that's fine. I asked a bit more about her work and she shared with me. I deliberately posted interesting picture because she mention of someone we knew and that generates her interest. Then it was done for the evening before i headed out to meet another attractive lady for the first time from the app. Will continue the chat with this new lady tomorrow and see how it goes along with her.
