Shall I end my marriage

[myw1]

We are married for 13 years and have 3 DCs. Things have always been rocky. Lots of fights and argument. I was never be able to make up my mind to walk out because of kids and it is still the case. Now I don't love him and don't have any passion and don't even want to have sex with DH any more. He is trying all he can to keep me and save the marriage but I just can't put myself into it any more. I have told him frankly how I feel but he is still trying. I don't know if I am depressed or not but I can't make myself to be passionate to him. It is a big guilt on me to end it because of the kids. What should I do?

I'd certainly do my best to be very sure and that I had tried all possibilities of getting back in love.
So, it depends on how much effort you have put on it so far, and how serious were the fights and arguments.

But, ultimately, you have every right to end a relationship if you want to.

What were the fights and arguments about? What has he said to you?

Possibly analysing them might unlock the key as to why you feel the way you do and, depending on that, you might either be able to attempt to save the marriage or realise that you can't.
