If you want to understand the dynamics of your relationship with this Leo man, you should not use Sun signs. They just don't give the info you need. Instead, you will get two birth charts, one for you, one for him. Both calculated off of the full birth time, the birth time, and the location of birth. You will compare the aspects (distances, in specific degrees) between planets in your chart and planets in his chart. Based on the number and type of positive contacts between your two charts, vs. the number and type of negative contacts between your two charts ... you will arrive at a conclusion. As for this Leo's negatives, there is absolutely no such thing as a perfect person. Every person you could get together with will have qualities you love and qualities you hate, qualities you like and qualities you dislike. In the end, the only thing that makes a marraige work is the ability of both partners to accept their spouse just as they are ... trying to change your spouse so they are "better" or so they don't annoy you or make you angry never works. All the "work" is done inside your heart, to learn how to tolerate those things that you don't like about your partner. Therefore, it is recommended that people not move in or marry until they have dated for a minimum of 2 years, because things are not always obvious early in the dating. It is super-important that whoever you DO get together has faults that you think you can learn to accept. Because it always boils down to this: if you can't accept the other, you will probably lose the relationship. Here's your first two "assignments" (based on what you've said): (1) He doesn't express himself for a while, and in the interim, you go absolutely bonkers. Hon, you are either going to have to learn how to handle that so you don't go bonkers, or you will end up losing the relationship. (2) No relationship will make up for our own feelings of insecurity. In the first 2-3 years of dating, this is generally not a problem, but as the honeymoon period wears off and people relax more into the relationship ... the more you depend on him to reassure you, the more frustrated and frightened you will end up becoming, and that is followed by anger and fighting. So you are going to have to work on improving your self-acceptance, self-esteem and self-confidence. You will have to do this for any relationship you wish to keep. Rest assured, there will be more challenges for you ... and he will have his own challenges too. Remember that the change always has to be within ourselves, because we cannot change others. Good luck to the both of you ... it's a worthy effort and if you take on the challenges and succeed, it leads to both personal happiness and to marital happiness.
