Is my marriage worth saving if my husband constantly puts his mum & step-dad before me?

that must be an horrible thing to go through and to answer your question no your marriage isn't worth saving...don't take this the wrong way but you need someone that is going to be there for you and take your side and from what i read it seems like he's stuck up his mother's *** and she has him tied around her little finger. If he loves you he will do the right thing but for now you can't put yourself through that. If he can't understand then im sure that there's someone else out there for you. Good luck.
