Romantic relationships in this and the next life

I'm fairly certain that the old algorithm will be abolished in lieu of a more dynamic one. The whole point of death is to level up, evolve and improve.

Well, it was Jesus' words and Paul confirmed them and additionally was giving us all to Jesus as His bride so.. I don't know how to take that aspect.

I also always kind of feel a bit disappointed when people say that the love between Christian brothers and sisters and love between yourself and Jesus is "better" than that of a husband and wife, or that they are "more intimate"

It's different rather than better, apples and oranges. You love God, your mother and father, your spouse, your children, your siblings and your friends all in different ways. Loving God doesn't replace loving your mother because they're different kinds of love, loving God doesn't fulfill a desire to love a spouse or children, because they are different kinds of love.
and sorry but sidehugs and handshakes certainly don't sound "more intimate" than sex. The very nature of a side hug is to keep distance between you and your christian brother or sister, not be closer and more intimate. Christians do side hugs because they fear the intimacy of a full on embrace.
So if romantic love is not a part of heaven it is not superseded because you have love of God and love of Christian brothers and sisters, romantic love is just missing, and romantic intimacy is just missing.
You have alternatives but not full replacements.
God promises we'll have joy and pleasure despite that.
But I still feel like I'm missing out.
