I too am in the same boat. Nothing is extremely horrid. But, we'll have a huge fight then it will be calm for a couple of days. I kind of feel like we are just barely getting by and not happily. I see a couple of options.
First off I could just through the towel in and admit that the last 7 years of my life were just tossed away (besides having my two wonderful children whom I love with all my heart) I am a child of divorce and know that the damage is truly unfixable with the kids, even if it is a friendly divorce.
Or, I could stay in it for the kids... but what kind of example is that for them? See a husband and wife with a ton of tension and anger faking it the majority of the time. I want to raise boys that turn into men and treat their women with the love, friendship, respect and faith that marriages should be built on.
I also could pretend that everything is peachy. Put a smile on my face and do all that I can to make life perfectly happy for my husband. (I've done this before and it worked we had about six months where he seemed genuinely happy) But one can only pretend for so long....
And last but not least, get some help. He is refusing to go to see a counsellor with me. (says that it is our marriage and no stranger is going to be able to do anything that we can't do ourself) But I have an appointment scheduled for myself next Monday.
Don't know if it will really help but at least I feel like I am doing something. Trying to make peace with myself and whatever decision ultimately comes out of this.
