Will me&my soulmate end up together in heaven after death

I believe so.

Ifyou both have accept Jesus as your saviour and belive what is said in God's Holy Word

If you both accept Jesus as your Savior you will both wind up in heaven.  But remember, you will recognize each other, but in heaven there is no marriage, just saints.

The post coital experience and accompanying cigarette afterwards may feel like heaven, but not necessarily for both of you.

Going to heaven when a person dies, has been taught by mainstream religion for many years. Does the Bible actually teach that all good people go to heaven when they die ? Acts 13:22 says this about King David. And after removing him, he raised up for them David as king, respecting whom he bore witness and said, ‘I have found David the son of Jes?se, a man agreeable to my heart, who will do all the things I desire." But yet, when David died, he did not ascend to heaven.

Acts 2:34
King James Version (KJV)

34 For David is not ascended into heavens:                                          Actually, the Bible holds out the hope of living right here on the earth for an eternity.    
Psalm 37:11
21st Century King James Version (KJ21)

11 But the meek shall inherit the earth, and shall delight themselves in the abundance of peace.
Psalm 37:29
New International Version 1984 (NIV1984) 29 the righteous will inherit the land
    and dwell in it forever.
Micah 4:3
21st Century King James Version (KJ21)

3 And He shall judge among many people, and rebuke strong nations afar off. And they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up a sword against nation, neither shall they learn war any more.
Micah 4:4
21st Century King James Version (KJ21)

4 But they shall sit every man under his vine and under his fig tree, and none shall make them afraid; for the mouth of the Lord of hosts hath spoken it.
 Some, as shown at  John 14: 2,3, will go to heaven when they die.  Jesus here shows that his faithful apostles, to whom he was speaking, would, in time, be in his Father’s “house,” in heaven, with Jesus. But he does not here say how many others would also go to heaven.
     Matt. 5:5: “Happy are the mild-tempered ones, since they will inherit the earth.”
     Matt. 6:9, 10: “Our Father in the heavens, let your name be sanctified. Let your kingdom come. Let your will take place, as in heaven, also upon earth
     2 Pet. 3:13: “There are new heavens and a new earth that we are awaiting according to his promise, and in these righteousness is to dwell.
