no not the end for sure. that is down to both of you, isn't it?
I don't know how long you have been married, but I am guessing a few years, right? i reckon your relationship may be in a transition stage - all long-term committed relationships do that. I mean it can't stay the way it used to be forever - we change, our responsibilities change, so our relationship changes. so you need to find new ways to communicate - i fought hard in the beginning of my marriage, well I should say we fought hard, to set up these ways of communication. it wasn't easy, to say the least, and we had no honeymoon phase bec of it, but frankly it has been so worth it. we didn't see anyone but worked with each other - bec that suits us better. I believe trying to find the right ways of communicating is very important and healthy for your children as well - they can learn.
your living situation doesn't help, that is for sure, but I am guessing you kinda need to given that you study etc, right? I would set myself a time goal when I would think it is possible to move out, and that is like your 'light', kwim? that way you know what you are working for - it always helps, even if it takes another couple of years.
finally, I think we all orientate ourselves according to the rel.ships around us, whether we aspire to be the same or try hard to be different - but in the end, our relationships are always unique, so don't compare, you live your own life. I tend to ignore any kind of comment regarding the possible difficulties etc of my relationship (my grandma has a lot of 'good advice'....) bec only I know what is going on. period.
all the best for you and your family.
