Always going be something there help

Ok so gunna cut this story as short as possible....

When i was 15 i was seeing this 21 year old completely fell inlove with him only did a few oral bits not full blow sex.any way when i was 16 he wasnt quick enough to say anything so i got with some other guy for like 6 1/2 years relationship that ended because i was fed up of how controlling he was and i meet my current husband we have a 3 year old little boy together and been married just over 1 year now! Been together for 6 years!

Recently ive been back in contact with my fling from when i was 15(im now 29)and everytime i see him i keep getting like butterflies and flirt like crazy! I know i shouldn't but its like i will always hav3 temptation for him and i dont know why! I hate the idea of cheating so wouldn't do that but it makes me wonder am i with my soul mate or not!

Part of me thinks if he said something 13 years ago we might be together now!

Im just so confused
