Will divorced and remarried couples be happy?

Can divorce and remarriage be happy or divided into the following situations:

1, if two people have feelings, then the possibility of divorce and remarriage is still relatively large. But if you remarry just for the sake of children, or for other reasons, then the chances of happiness are not particularly great.

2. If two people choose to separate because of some unavoidable reasons, but their love is still deep, then after remarriage, their feelings should not be affected, that is to say, they can continue to live happily. Therefore, when choosing to remarry, we must consider whether the later life can be happy.
