How old are you?
Why does your family object to you dating, having a boyfriend?
Why does his family object to him dating, having a girlfriend?
You both sound young but you are both University students, correct?

The way he is treating you now is not right. Think twice about calling him your One True Love.
Maybe he was just your Love 101 class. ??
Love is complex and we can get stuck in it and stuck in obsessing on the object of our love.

As for your state of mind, you are seeking all your value, self worth, pleasure, your moods, your thinking, on an external source – your ex-boyfriend who sounds like a boy to me. If he loved you he would tell his dad enough and find time to date you. The way he is behaving now in your social circle is unacceptable. You need someone More Mature. Don’t get caught up in the emotions of a first Love and bravely move on and discover the world waiting for you filled with love. But you must center yourself and go out and project yourself as centered and willing to love again. The centered part you cannot fake, that you must find within yourself and reshape your own internal emotional landscape.

Sometimes we think we will never get over these romances. YOUWILL. Be brave and move along the down the path of your life and find out what is waiting for you around the next bend.
