I think in this society we are taught that there is something wrong with us if we are not in a relationship. But I think at this time, you could start focusing on your child instead of that rather narcissistic man with whom you were involved. The thing is he robbed you. He also robbed your child of time with you. However, the good news is that at least you can see who and what is important to you now.
To promote a better sense of yourself I think you can also concentrate on your new theatre company. What an exciting opportunity!
I bet that you probably are quite relieved that you have parted ways with this man and that you have your child and your life back. I can also bet that your child is rather happy too!
God Bless!
