My boyfriend told me that my first love texted him and chatted with him.

At least it shows that he is not the kind of person who loves one and loses another, and it is the first love, and no one can forget it. In fact, if you were you, could you completely erase your first love from your heart? Only now his first love has appeared in his life, but he is married and has children. Your boyfriend is not stupid enough to be a third party because of nostalgia. After all, he has you now. As a man, I think it is most important to cherish what is in front of me, which is understood by most people.

So, what you have to do is to let go of these doubts, respect his past, be kind to him, and squeeze his first love out of his life, although you can't erase it from his heart. As long as he loves you, that's enough.

As for you saying that the two of them still have feelings, maybe you think too much. After all, people have been together, and the tacit understanding is normal. After a long time, you two know each other better, and you can have this kind of dialogue or tacit understanding of your eyes.
