I like myself and can't forget my first love, but even if he doesn't have a girlfriend, I won't take the initiative to get him back, mainly because I feel like a girl and I won't take the initiative again. I can't help it Girls are the kind of creatures who would rather miss than take the initiative. I think if they miss, there will be a gap and then they will get back. Old love rekindled may still repeat the same mistakes. First love is beautiful, don't do it. What's more, the first love already has a girlfriend, and we can't do this. This is immoral. Interfere with others' feelings and affect others' lives. What if we get it back? Take a bad name, break up others, and fulfill yourself.
So in my opinion, don't chase this situation, don't disturb other people's lives, let our first love stay in memory, and don't ruin it.
