Why does God allow relationship breakups?

There is a reason why this happens. One reason can be found in Ecclesiastes 3:1 and this is what you can read.

"For everything there is an appointed time, and an appropriate time for every activity on earth: "(Ecclesiastes 3:1, Net Bible)

We know that the break up is one of the causes of young people getting desperate. Worse, they neglect their own bodies and some even commit suicide because it is difficult for them to accept reality.

Indeed, it is hard to become a victim of breakups but in Ecclesiastes 3:4, here is what we can read.
"a time to weep, and a time to laugh;"(Ecclesiastes 3:4, NRSV)

If we read the Holy Bible and listen to the wisdom of God, He really allows this to happen to our youth. It is only Satan who discourages people to overcome all problems that come to their lives. The Bible says you will not be given trials that you cannot cope with.

"He will not let you be tried beyond what you are able to bear."(1 Corinthians 10:13, Net Bible)

For some reason, those who experience this situation can serve as inspiration to others. You cannot understand any situation if you will not experience it.
It happens since God wants to show there is destiny for everyone (except for those who are meant to become priests and nuns).

"Do not be afraid, because from all eternity Sara
has been destined to be your wife. "(Tobit 6:18, Christian Community Bible)

We need to have acceptance. This cannot be rushed. However, if we implore God’s guidance, he will lead us and show us His plans for us.

"For surely I know the plans I have for you, says the Lord, plans for your welfare and not for harm, to give you a future with hope."(Jeremiah 29:11, NRSV)

He is the best provider of partners.

"House and wealth are inherited from parents,
but a prudent wife is from the Lord."(Proverbs 19:14, NRSV)
