I didn't say to agree to anything. I didn't agree to a divorce. I just told him I understood that was what he wanted, that I didn't and because I didn't I wouldn't help him. Can I stop him? No. Whether I or you or anyone agrees with a spouse who wants out, the legal system does not require both parties be in agreement to get a divorce.
Has it helped me that I didn't agree? I don't know. He hasn't filed anything and it's been almost 3 years post bomb and close to 2 years since he moved out. I focus on myself and our D's. I make plans and live my life. I still get blindsided by life at times (it does get messy you know), but I'm a big girl and I can go get my own straw and suck it up.
Will stomping your feet keep him with you and more importantly in love with you? Is fighting with him (as opposed to for your marriage) going to get you where you want to be?
Time is on your side esp if your state you can stall 2 years. Be amazing. If you forgot how, learn again.
Learn to be non-reactive esp to provocative statments. It will allow you to think about what is said and then come back with a response if you choose.
