Attempting is always good, but imo:
Boy: I have to tell u that I thing u look very nice
Girl: I have to go im in a rush
Has less chance of working than: "Hi, ...we should have sex. what's your number?"
So after attempting the next step is improving the attempt.

I haven't seen anyone tell him this yet since hes a noobie, but make sure you're scrubbing those pheromones off, especially NONE. NONE is hard to wash off, and definitely don't spray it onto your clothes although people have said oxyclean is good for cleaning your clothes. He could be ghosting, besides the bad approaches. Less is more, with mones and your game. Girls will know instantly if you're desperate or trying to hard and will reject you right away. Work on your body language, don't put on too much none based products at once, and be more relaxed and cool with your approaches. I'm honestly horrible at approaching hot women so I commend you for having the balls. I'm better more relaxed or if she talks to me first...which mones can actually do for you quite often. sometimes all you have to do is be near hear, make eye contact and smile. Not bum rush her and ask her to smell you. Let it be natural sometimes
