weird question..

Can you love your SO so much that it becomes a sin? Also I have a few added in questions, if you can't get married yet but want to be married in gods eyes and both asked god to see you as married is that possible? Ik that seems ridiculous but it makes me wonder.. and we have Been together for four years but can't get married because I am 17 just a year away and it breaks me that in my heart I feel so close and want to be married but can't so therefore feel I can't be intimate without it being a sin because of a law😩
