Lavender, my heart goes out to you. I know it’s hard to believe but time is a healer and the day will come when you will really feel there was a reason why this person had to enter your life and maybe there is something positive you will glean from this relationship that will help you when your true zivug comes along.
You sound like a warm and caring person and with Hashem’s help you will find the right man who will want to, and have the ability to share his life with you.
