Crystal, I don't know how old your son is, but I am having the opposite problem with my teenage children. It started out with them asking me when I was going to start dating at a time when I was not ready. But when I was ready, I kept them informed that I was dating. Now that I've met someone and I am in a relationship, both of them just flipped the narrative on me and now are resisting the idea. I never expected them to be engaged or for us to be blended family, but now they are even opposed to my boyfriend being around them. And it has nothing to do with my boyfriend. It's their way of communicating that they are not ready to see me with someone else.

Children have a way of processing divorce differently. I am not certain we single-mothers should make decisions based on what our children want (for a step parent or not).

You pursue your love interest at a time and pace that works for you, and your son will eventually adjust to it.
