For the first time, I have crush on LEO MAN. HELP ME

You are getting too worked up over a guy you do not know. Leos can come on strong in the beginning, but take it with a grain of salt. He may have a busy life, he may have other women that he is talking to, he may be playing games to see what you do, or he may be insecure that the date was not "perfect". You simply do not know, so do not put all of the worry on yourself. Do not let it rattle you. Reach out to him and let him know that you had a great time and would like to see him again (men need to hear this kind of thing from women at times to know if it is worth moving forward). After that, see what he does. Do not wait for him to respond, just go about your life.
