The thing is, you dont just stop loving someone overnight. If you've been together for sometime then he will have memories to. He will be reminded of you as much as you are him.
If you were to go overseas for a while, how do you know you will have to come back to the same thing? maybe if you did, you wouldnt feel you needed him anymore. You would see new things and be in other places and that would take your mind off things. It would give you BOTH some space to find your feet again, and you WOULD become the person you were before.
do you mind me asking how old you both are? you can tell me in a PM if you prefer, or not tell me at all. I dont mind, I just wondered.
