My boyfriend had a girlfriend before me in high school. Sometimes she often thinks back to high school, which I can understand, because high school is also very beautiful for me. Even if he said he wanted a girlfriend, I don't think it matters. Because after all, it's all over, and now it's you with him. And if a person really wants to, his predecessor will not tell you easily. He can tell you so indifferently and recall his college life, which means it's just a memory. People always miss the past.
Because I know that it was a trip that I can't go back, and I will remember it as long as he is good to you now. Cherish you enough, then it doesn't matter how many memories he has. On the contrary, I feel that I will recall my former boys, which is particularly emotional. I'm sure he won't have other ideas. So you must give her enough trust and confidence in your feelings. Don't be too suspicious, lest you hurt the feelings between two people.
Just like I sometimes recall the meeting and first love in junior high school, it's just a simple memory, only thinking of youth and immaturity at that time. Not that I want to go back and get back together with my ex.
