My wife left me for her first love, will she come to her senses?
	
	
		My wife and I have been in a relationship for 18 years, we have been married for 6. We have two children, girl 11, and boy 8. 3 months ago my wife found her first love on face book, without me knowing, hooked up with him. They got very intimate with each other. She told me she wanted a separation at first, to find her happiness. Then she spends a month in his house, 550 km away. She eventually returns to the family home and now wants a divorce. 
She wants the children 50/50 but because he lives so far away, she wants to live in a rented house near the kids so she can have them for a week, then fly to his house and be with him and his 2 boys for a week. He cannot leave his home town due to his ex wife’s instructions and I won't let my kids leave this town. She knows she has to find 2 jobs, one in each town, week on week off. Has she lost her mind? How can a mother sacrifice her children's happiness and family to be with a man only half the time? Will this relationship last? Will she come to her senses? Is this just lust? 
She says she loves him so very much and that she has thought about him off and on for 18 years. She says she no longer loves me. How can she forget 18 years together? Is this just an infatuation? I have always been the sole provider for our family, I have never hit my wife, I don't drink, I am a good father and husband, and so why is this happening? I am so lost and alone, so very heartbroken. Can someone please make sense of this?
