Polls: Break Up & Divorce

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.

Do they usually come back?

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?

Just under a month ago my ex tried to add my mom on Facebook. This ex and I have not spoken in 4 years. He didn't like my mom when we lived together but she helped him as best she could by getting him a job and phone and letting him live with us. We had a lot of firsts together and I cannot stop wondering why he reached out to my mom of all people. Mom called me and asked what I wanted and a day later I told her to deny it. In that time frame he deleted and resent the request. He never messaged her or myself though. Should I reach out and ask him what it was about or leave it be? Both myself and my mother are in long term relationships and I don't think he would intentionally try to manipulate me. It was a 3 year relationship that lasted from 15-18 but we met and I originally fell in love with him at 11. He had moved away and as soon as we could we were together. After the breakup at 18 we stayed in and out of contact and hooked up for 6 months when I was 20. Since then there's been no contact and I don't know what to do and cannot stop fixating.

Hi, I'm looking for some advice please 😊 I have recently broken up with my now ex boyfriend, due to a gambling problem, drinking issue, questioning my worth, financial issues and his negative attitudes and behaviours. He wanted me back and is saying he will make changes, I know he has quit gambling, not drinking as much and he's saying all the things I want to hear and have in my future and would do anything to have me back and saying it's me or no one.
I've been asking for the last 5 weeks since we broke up to give me space so I can decide if I miss him, he can implement these changes he is speaking of and I can have some alone time to decide if I do really miss him and want to try again. Thoughout these 5 weeks he has smoothered me, begging to take him back and telling me there is no one else, he will never date again, he wants to marry me, have a family and will support me and be a better person. he's even offered relationship counselling and said he will do anything to make it work.
Two days ago I said no let's call it a day I'm done I'm not willing to give it another go, his pushing for an answer was exhausting and it's was pushed me to say no I'm done. He has then done everything I asked yesterday stopped the messaging and then sent a quick one this morning to say he'd removed me from social media not to be petty or vindictive but for his own mental health. Since he's done that, I regret it he's never left my head, I can't stop crying and I feel sick. What should I do?

There is no way I will be back with my husband
