1 Corinthians 7:7
"I wish that all were as I myself am. But each has his own gift from God, one of one kind and one of another". ESV
"All". Paul is addressing the church as in 1 Cor 1:2. "to the church of God..". All of the church; every member is included.
"I wish". Paul expresses a personal wish but submits it to a higher authority. Every member of the church has a gift from God. Nobody is exempt.
Conclusion: Within the context, which is of marriage and singleness, whatever a member of the church has , has come from God.
To me this verse is very simple and clear. The problems arise not from the verse itself but from the church not having yet attained to the "unity of faith" Ephesians 4:13.
Christians who believe all human actions are derived from "free will" will read it one way; Christians who believe that all their actions are an outworking of God's sovereignty will read it another way and those Christians who believe that both of these are ultimately compatible will read it another way.
In your question you use the phrase "against their will".
"You will seek me and find me, when you seek me with all your heart".
If God predestines/gives someone to marry or not marry and that goes against what they were hoping for, then, if they follow God's leading and obey against their feelings, there is a sense in which what God has for them is not against their will if it is their will to seek God with all their heart.
It is only against their feelings.
"And we know that for those who love God all things work together for good, for those who are called according to his purpose."
If God does lead someone into something that they were not expecting to make them happy and fulfilled, then, because He loves them they will at some point, one might expect, be shown why what He gave was good for them. And their feelings, in time, come into line with that.
In looking at any Bible verse there are two things interacting 1. God's Word and 2. Us.
I suggest that 1 Corinthians 7:7 is very simple. I suggest that if it appears complicated we may not have examined ourselves and realised that our lack of clear thinking and the state of our faith may have resulted in our having undefined presuppositions regarding "freewill" and predestination.
