S.H.
My friend's Husband, did that.
But it was very hard.
When a spouse/parent is back in school, it requires a lot of time/dedication and time away from home... to study and go to classes etc.
Even if some classes are online, it requires a lot of time. And time to be ONLY studying. And the rest of the family, understanding that.
My Husband went back to school too, after we had kids. So I lived it too.
During the entire time my Husband and my friend's Husband was in school... our Spouses were not just available any ol' time. And scheduling things, was done according to the Student Spouse. LOTS of times, continually, my Husband and my friend's Husband, could NOT make it to most family holidays or gatherings. Because, they have tons of school work and projects to complete as well as keeping up their grades.
Anyway, while my friend's Husband and my own Husband was in school... THAT was the, priority. I was like a single parent, while my Husband was in school. My friend was like that too.
There are many non-traditional students nowadays. ie: parents.
Once you go to school, you NEED to, make sure you and your Husband talk about it... and make SURE he knows and realizes... that you will NOT be able to do and be, everything for everyone all the time. HE WILL HAVE TO... .help ALL around, and with the kids and with the home and with everything. If he does not help and pick up the slack for what you do not have time for... there will be lots of conflicts. And you will be very stressed.
The Student Advisor, at my Husband's school, made SURE to tell students who were married and had kids... that it will be very, strenuous. Because, going to school requires a lot of commitment and toggling their roles as a parent and spouse, at the same time, is not easy. And in fact, per my Husband's college program, the Advisor said that some married with kids students had marital problems (and divorces) while they were going to school. Because of the time commitment, of going to school. So that means, your Husband/family, will have to all understand your "job" as a student. Because your going to school, will impact the family.
Your Husband AND kids... NEEDS TO KNOW, that studying is your priority. And that they ALL NEED to help. You will not be available lots of times. When my Husband was going to school, my kids were great about it. They were young. They understood. They understood that when Daddy was studying (which was all the time), they could NOT go in that room and disturb him. BUT he did make time, on his breaks, to be with them and do things. And he would show them what he is studying, they understood why Daddy was studying. And when he graduated... they were SOOOOOOOOO proud of him, and seeing him graduate.
It was a good life lesson for them. Seeing their parent, studying so hard, for a good cause.
Being a student-parent, requires LOTS of discipline. On your part. And the others.
And even if you have online courses, that does not mean it will be easier. My Husband had online courses. And it still required lots of time. Undisturbed time. And there are still deadlines etc. and requirements to interact with the Professor and the other students in that "online" group.
My Husband was in school for close to 4 years.
My friend's Husband, was in school for about 2 years.
So, you need to and your Husband needs to, UNDERSTAND that... timeline. Of being a student. Your family has to understand that TOO.
ie: there were lots of times, my Husband could NOT attend family functions. Due to his school commitments. Me and my kids would attend those family gatherings without him. AND I would have to "explain" to the other relatives "My Husband couldn't come, because he is studying....he has a project... he has deadlines...." And not all relatives, understood that. So I ALSO had to also deal with, other relatives/family irks & snarky comments about it, like "Well he should have made time to attend...." etc.
So you need to also realize those things too.
I did NOT make, demands upon my Husband while he was going to school. All those years. School, was the priority and the time he needed, for it. I tried to make it as easy upon him as I could. I wanted him, to do well, and get straight A's. But it was not easy, on me. It was stressful. But you suck it up.
IF that graduate degree is something that you REALLY want, AND WILL USE... and then pursue a job in it, then sure. It would be something to do.
BUT, if you are just pursuing a graduate degree, to keep busy or to pursue some idealization, but will not... use that degree for getting a job in that field, then... you need to rethink, your reasons... for wanting to get that degree. Because the bottom line is: Is going to school for your Masters, necessary? Or not?
My Husband used his degree to get a better job. And he did.
My friend's Husband as well. For him, it was REQUIRED to have a Masters, for the position he was being groomed for.
