I think whether to be the first to initiate communication really depends on how you guys left it. If, since the time you separated, you have not clearly communicated to her how you feel about her, what her presence in your life meant to you, and offered a heartfelt apology (if necessary), then perhaps you should. If you already expressed everything you wish to express to her and she has chosen not to respond, I’d let it be and continue forward in your life. You know in your heart of hearts and based on your own intuition if a further explanation or words of affirmation are needed from you to her. If you’ve said all that there is to say, you’ll know that. My trusted advisors have all told me that there is nothing more for me to say. In my case, they are correct. Now, in all honesty, if you do reach out and communicate, I don’t think that will cause some shift in the cosmos and ruin destiny. What will be, will be. Just, if you already have spoken your piece, don’t torment yourself and keep reaching out to someone who is ignoring you. That would just further perpetuate the cycle of vulnerability and rejection if you have reached out and she’s ignored you.
