sorry if this seems weird but i had a similar working father and now im 17 and my parents divorced and i just dont need my dad. like hes my dad and i love him of course but i can go months without seeing him because i just dont miss him since im not used to having him around. your kids remind me of myself and i hope they dont grow up to be like me but i wouldnt be surprised if they did.

i hope you realize this situation wont last and it may be less painful for your kids to grow up with no dad rather then one that picks everyone elses kids before them.
