I know its hard now. Believe me I also left my partner when my son was a similar age. He is 12 now.
It takes time and patience to heal a broken heart. Even though my head was saying my ex was no good for me, my heart told me otherwise.
Still kept contact though and I don’t like seeing him at all but I will have to. Everyone has to do things they don’t like, unfortunately.
I started going surestart centres and they were a god send. I went to the classes they offered and volunteered once my lad qualified for free nursery care. I’ve since been on a CBT course and more recently a stress management course both self referred. I started work again 5 years ago and I’m now looking for a new challenge.
So you see you can make your life as you want it. Date, work, do courses you can do what you like now. And it will get easier promise. 😀
