I'm don't know what to think :(

Girls so i was dating this guy long time ago, we were dating for 4 years but it was so complicated but we were always there any time... i decided that i didn't need a relationship like that... i deserved more. I prayed to God to meet the love of my life and then it happened. I married the love of my life the one who i want him to be the father of my kinds. He is so so perfect and I'm so in love with him but one night i had a dream about my ex and i don't know what is going on but it is happening more nights. I really really just wanna know about his life, add him on snapchat or i don't know but I'm so afraid about loosing my husband only because i wanna know the life of my ex.... this is so fucking hard :(
