it is hard. You should commend yourself for making it two weeks!
No contact is my biggest struggle. I have three children with STBXAH. I have to maintain minimal (extremely minimal - once a month texts regarding visitation and company business). English Garden is right on the money.
He only contacts me first if he needs something and then he expects immediate responses and reactions. When I don't respond, the texting ramps up.
Someone on here once said to me that 'no new contact is no new pain" . It has been completely accurate to describe it that way for me. When I do get sucked in to a new conversation on the phone, it leaves me horribly upset. Promises that will NEVER happen, pleading words, I love you's, the whole she bang, everything that I want to hear. But he is all words and no action. And he is on a steady decline.
Be gentle with yourself.
I know how badly loving an addict hurts.
