I agree with the last answer. Why is it that misery loves company ?Anyway it is so much easier to blame someone else then to face the truth and admitt you were (he) was wrong. Sounds like he wants to be right all the time. (USUALLY) It is easier for women to say the I am sorries but for men it takes alot of pride. In most cases a mans ego can be hard wall to break through. Hopefully once you get through the hard exterior he will be easier to deal with when a problem surrounds the 2 of you. marriage is hard work. You have to make the decision is it worth the fight to survive. I hope that if you do decide to stay in the battle that both of you are on the same side fighting for each other and not against one another. Will your love conquer all ? or just your relationship ? Also moving in with eachother is a major step into commitment. We all know women mature faster. This is the first step into a full time serious commitment. He now has to learn to involve you in almost every part of his life. It can be very frustarting. I imagine that you might understand a little bit of that. You must of had to make some sacrifices to move in with him. It is easier for women (most of the time) to take that next step in life and want to settle down, get married, have children, and grow old with someone. The other sex is a mystery that's for sure but then again so can women. we are much more complexe. I also wonder, Maybe he likes arguments. Not all guys but alot of them like to fight, wrestle, and be boy's. What if it's just in his nature ? Or like I said it might just be harder for him to adjust to the new life that awaits the two of you. What ever the cause only he knows the answer and only you can make a decision. I am curious how old are the two of you ? and how long have you been living with eachother ? Everything that is worth something is going to have a price whether it might be worth it is up to the both of you to decide. I wish u the best of luck.
