There is hardly a man who will be pleased to know that the ex-husband or boyfriend of his beloved was with her more gentle, attentive, talkative, passionate, etc. Such conversations almost always lead to misunderstandings on both sides.
When a woman starts such a conversation, she expects understanding and attention from her man, which she, apparently, lacks. The man considers these conversations paradoxical, and not without reason. To get the best idea of how humiliated your loved one is, put yourself in their shoes. It’s unlikely that you will be pleased to know that his ex made this salad tastier and “in general, she had something to talk about”.
It is important for a man to know that he is the only one with you. If you love him, do not say, "Sleepy, you stretch almost like my ex" (he simply will not tolerate this). It would be more appropriate to say how you like to wake up with him in the morning. Focus on the best features of the person you live with or are dating now. While highlighting the positive aspects, try to feel his personality. Remember how he was able to attract your attention? After all, if he managed to interest you, then it means that there is a unique originality in him?
Respect your feelings and attitude towards each other. If you intend to have a heart-to-heart talk, consider whether it will be pleasant for both of you to stir up the events of bygone days in your memory. Even if one of you speaks unflatteringly about past relationships, this clearly does not add zest to your or his positive image. After all, independently of each other, you will begin to analyze behavior with other partners, projecting it onto your current relationship. Even if you agree not to return to this topic anymore, the memories of it will haunt him and you for a long time.
Consider why you think about your ex so often. Maybe because your feelings for him have not cooled down yet. In this case, you should sort out your own experiences. You may need the help of a psychologist for this. In any case, you will have to choose between two men. In whose favor it will fall out is up to you, but the longer you wait, the more difficult your life together will become.
