No it's not that women's emotionally unstable. It's women think everything from an emotional POINT OF VIEW. Things to a man is just a thing but to a woman, it ALWAYS has some emotional connotation and meaning to it. I will give you a simple example: Going out for dinner. To a man, going out to dinner is just to get a meal, getting his stomach filled instead of eating at home. But to a woman, going out could be getting away from it all, a whole new experience, the man taking care of her, caring about her... Women KNOWS that men don't feel things from an emotional point of view as much as women but the fact that the man went out of his way to try to think from the perspective is what women appreciates. It's the gesture and the thought that counts, not necessarily the actual thing. Men always want to give women tangible things and women want that too but it's more of the thoughts BEHIND the tangible things that women treasure more. Of course every woman is different, some more emotional than others but if you can bear in mind this, it makes things a bit easier.
Unless she is diagnosed with some other conditions or illnesses, your ex is just not a good person, everything else aside.
I already have kids. Women don't have a problem having kids with me out of wedlock, I just haven't picked the right one(s) yet.
When you think about all the time being wasted dating, catering, and pleasing women? For every hour spent in a dumb argument with your girlfriend, when it could have been better spent doing something productive. For every hour putting up with the B.S. that is dating chasing after girl after girl that could have been better spent doing something more productive. It's no wonder that the greatest civilization in history had arranged marriages as the foundation of it's growth.
Lots of ways nowadays, artificial insemination, sperm banks, live impregnation. This man had 106+ children by just impregnating women all around the world on top of donating to sperm banks: https://www.gq.com/story/how-to-have-babies-sperm-donor-ed-houben and he is not stopping. And he is passing the torch to his son too. Science is the limit nowadays.
I got an ex too that is still giving me weekly telephone calls that i've never answer but she still doing it even though it's been over a year now. Closer to two years. I suspect that she is approaching the age where her biological need to make a baby is the motivation. I would go back to her, but then I think about all the crazy.
Dating is NOT for pleasing women. LOL Dating is supposed to be a way for you to get to know your partner before potentially becoming life partner with her. We had ample chance of getting to know the person before marriage and we still have so high of divorce rate, you think marrying someone without even knowing that person at all via arranged marriage is any better? It only SEEMS that the arranged marriage is "better" in those old times because 1) divorce was not allowed except in extreme cases and definitely not initiated by women and 2) polygamy was allowed. When the man was no longer happy with the first wife, he could just go out and find other women. If you subject all the marriages in the old times with the standards today, the divorce rate back then would've been 100X higher.
You need to move on. I believe in trying my best to make a solid and supportive marriage but once the marriage is over, it's over. UNLESS something FUNDAMENTALLY changed or you see something SIGNIFICANT now that you have never seen before and that SIGNIFICANT thing is really game-changing, it's not worth it to go back to a marriage. I mean the marriage failed the first time for a reason, UNLESS that reason for failure is no longer existing, what makes you think the marriage won't fail the 2nd time if you go back to her? What if it fails the 2nd time? If she is so keen on you now, WHY did she divorce you in the first place? She needs to move on and you need to move on too. Maybe you and @nooby_mcnoob should get together and @nooby_mcnoob can introduce you to some women.
