What exactly are you scared of? Why are you scared of telling him?
You know, you will feel so much better when you have told him. You will be able to move forward, it will make such a difference.
Why don't you write it all down in a letter, don't say anything nasty, don't direct the blame at him but, just tell him how you feel, how you feel you have nothing more to give to the relationship and you want to go your own way.
You are allowed to want out of a relationship that isn't working for you, you don't have to have his permission, he doesn't have to agree, if it's what you really want then you just go for it!
We will support you through it, you have nothing to fear only lot's to look forward to!
At the moment only one person is blocking your personal happiness and, that person is you!
I am sorry if this sounds harsh, it is not meant to be harsh. But, you have to believe in yourself, believe in what you want and what you want from life and, take the biggest leap of faith!!!
We are all with you!!
Right, I'm off to the tip now, it's great destresser! but I will be back later to check up on you. You keep smiling and keep strong. Do something nice for yourself today. get away from the house, from dh, leave him with ds and you go somewhere quiet and do some thinking, and some writing!
Have a lovely day! xx
