Mentally
First of all, the ex who has been in contact for many years is always a pain in our hearts, because we didn't meet our ex earlier, but fate is such a wonderful thing that we finally came together.
However, looking back on my predecessors, I am still a little sad. After all, I'm not the only one he loved. We always want to be the only one, but we are still too late.
Especially when the incumbent is in contact with his predecessor, I feel even more sad, because after all, the two of them once had a relationship, and their contact may spark a new spark in this relationship, which is unacceptable to us, so we will mind very much.
Sometimes whether he contacts his predecessor or his predecessor to contact him, we will mind, because we know that the two of them once had feelings, and we are afraid that they will rekindle their old feelings, which is what we care about very much.
We may also be afraid that others will know that I have an ex now, and it is the kind of ex who has been in love for many years.
Never mind.
In fact, there are many things he doesn't mind. Now that he has chosen you, it means that he has cut off all ties with the past. Otherwise, he will be with the person he has been in love with for many years.
From a realistic point of view, he chose you now, which means he recognized you now. No matter how deep their feelings are, you still beat your predecessor.
As long as you are good enough to him, don't mind other people's past, especially your present past. You chose him now, because he can only become him now if he is with the past, and if he has no contact with his predecessor, you don't have to mind this at all, because that is a thing of the past. It is meaningless to look back on the past, and it will also affect our present feelings.
Speaking of whether you should care about your ex who has been dating for many years, personally, as long as two people don't contact you, you don't have to care.
A person who appeared in his life in the past will not affect your current feelings. If you mind, it will only make the incumbent feel more guilty about his predecessor, so personally, you don't mind if you don't mind.
When you really care, you should keep it in your heart silently. Don't have any conflict with your current predecessor because it's not worth it. What you have to do is to live a good future life, not dwell on the past life.
