Polls: Break Up & Divorce

I broke up with my boyfriend. He isn't taking it seriously. Because, when we argue sometimes I block him. But, I actually do want to move on with my life without him. I feel kind of guilty for blocking him because I think it feels cruel. But, I don't want him saying sweet nothings to me to where I FEEL like working things out.
We have fundamental disagreements. He had inappropriate online relationships when several different women. He has stopped the inappropriate conversations, but he still talks to them from time to time. Even though they are regular conversations NOW, it doesn't change the fact the he is still in contact with these people.

Sad to say, but the question was inspired by my parents.

My mom was and still is miserable being with my father and talked about leaving him a lot growing up, but never did. She has become extremely bitter, even now, that she didn't do more with her life because of his expectations of the women in the family and now his medical issues forcing her to care for him even further.

Me and my man have many arguments
Even over small things
We have broken up several times
And im always the one packing my clothes when we fight
Him saying "im done, i dont want to see u again, i will not message/call"
Vice versa..
But 90% of the time he calls and tries to come back to me
And we get back together

Then yesterday morning we had a good time just going to a park and joking around
And having a laugh

Then we got home and we had an argument about a tv show
And then he got angry and just broke up with me
"Im done, you always argue every week, im done with your crap, i can't take this anymore"

And then we bickered back and forth
I started packing my clothes
Then he said
"F**k this. I dont deserve this. I dont love u anymore, I dont care about u anymore, go find someone else"

And then he dropped me home
He was still angry

Is this final?
How could he switch to not loving me and not caring about me in 1 second?

I’m in love with this guy, completely in love and I don’t know how to move on. But I need to no matter the amount of love I have for him; it’s just creating pain.

If I move somewhere or travel for about half a year (that’s all I can afford and do want to return home) would that help me move on? And I mean to another country or the other end of my country. A substantial move.

They've been separated from their spouse for a while, but neither of them have filed for divorce. Would you continue seeing them or break up with them?

i know im not over him. i blocked him on everything to help me move on but it never worked. i thought i would just unblock him when i dont need the "barrier" anymore and when I've gotten over him. lately I've just been thinking about unblocking him. i do not plan on talking to him. would it make the process of moving on just worse? probably not. right

Merely...

Me and my ex boyfriend got back together recently after a year of break up
We were together for 2 years

He was in another relationship after our breakup
But they didn't work out

He was scared to talk to me again but he end up messaging me
So we started talking
And then dating again

He told me:
"You know I always used to keep looking at your facebook profile few times a week.. to see if you're still single or have a new boyfriend"

Why would he do this when he was in a relationship before?
