You are entitled to a relationship. Just make sure your son knows he won’t be loved any less and your girlfriend won’t replace his mother

I am a 44-year-old man, with a seven-year-old son. His mother and I are divorced, and I moved out when he was three. We share custody; he is with me three days/nights a week – including part of the weekend. He is doing well at school and has varied interests. He is a very happy child and the most precious thing to me.

I have been in a steady relationship with a remarkable woman for three years. She and my son get along beautifully; he looks forward to seeing her and she loves him very much.

I’ve been considering remarrying. All the ingredients of a happy life are in place, but I am worried it might have an adverse effect on my son. I do not want to introduce any confusion into his life.

While he has spent loads of time with my girlfriend and I, it seems he has yet to grasp that we are in a relationship. A few months ago, he heard me refer to her on the phone as “my girlfriend” and said, “I thought she was your friend. I didn’t know she was your girlfriend.” We didn’t discuss it further and I took care to never refer to her as “my girlfriend” again.
