Pisces
Anyone can be a Pisces sweetheart, that is really full of "big love", for the view of the ex, Pisces feels that the love is still there, even if they are separated, it can't be stopped.
I don't know where Pisces is so affectionate a day, it is really a "love species" that has nowhere to place, as long as the ex is looking for him, it is also responsive.
Not only can't let go of his ex, but anyone who has had something to do with him, Pisces can't let go.
Cancer
Who do you say Cancer loves the most?
It must have been the ex, and after the separation, he knew that he missed it.
Cancer can't let go of the feelings that he has really paid, even if he knows in his heart that he can't go back, he still leaves a place for his ex in his heart.
In Cancer's heart, the old love is always the best, and that is the trace of their own growth.
Even if they have a lover again, Cancer will still miss the old relationship in their hearts from time to time.
Capricorn
Capricorns may seem aloof, but they are just not very expressive and like to bury their hearts in the depths.
In the case of the ex, Capricorn is very unable to let go because he has poured too much into the relationship.
Capricorn is a person who has a plan to do things, and since he is in a relationship with you, it proves that he wants to go to the end.
But in the end, it backfired, and although Capricorn had no choice, he still couldn't let go of it.
