How can he replace me just days after our breakup?

men process emotions longer than women. He js needs to fill the void

man here. I was together withbmy wife for 12 years. the last three years where really toxic. 3 years before it was ok. the 6 years before it was one of the best times i ever had. after 3 years of constant fighting we broke up in a huge fight. She started seeing a work colleague as freinds just some weeks after. she told me 3 minths after that she was seeing someone and shes really confused. but he has a girlfreind. After that I oanicked and started dating a colleague of mine. i ended it because i saw it was just rebound and was panicking. Now she confessed to me that her and him confessed the feelings for each other because he was already unhppy in his current relationship. it is really affecting me but also i am reliefed. I wish them all the best but it seems to me like a rebound (as was mine). At least for one of the two. Now I am really focusing on moving on and not on getting her back. I told her nit to tell or ask about my or her feelings. Only kids things.

I can say that bith people in the breakup are extremely hurt. noone breaks up after a long time because they like it. In my case she did it to protwct herself. I also was already talking about brwakup so many times but couldn't bring myself to do it. It still hurt when it happened. We both hurt eachother so much that we cannot come back to a basis of trust on that deeply emotional level. On the parental level the trust is there still.

Long story short: There is two extremely hurt people in a brwak-up and all do things they think is best to soothe the pain. jumping into a new relationship rwally early almost always goes wrong. so stay strong and look towards the future. lwarn to be comfortable while you are alone. do sports. thats what helps me

My ex cheated on me after 7 years and they are still dating. I think they are both on the rebound. I have not dated anyone and it's been 10 months. That's not fair to the other person to do that until I'm completely over it.

was he the type who avoided hard conversations or emotions even during the relationship?

Because it's their coping style, they want something that's easy and fills the hole in their chest, but when it gets too close and too real, they dip and repeat the same pattern. It's nothing to do with your worth, it's everything to do with their lack of accountability and capacity to love properly.

my ex moved on in the week prior to us breaking up. it is incredibly painful

i’ve learned that when someone moves on in 2 days, it usually says more about their coping style than your worth. rebounds are loud distractions. 3 years don’t just disappear in 48 hours.

my ex was “talking” to someone new within a WEEK. i kept thinking how do you just erase me like that?? but honestly… it wasn’t that i was replaceable. he just couldn’t sit alone with his feelings. some people jump fast so they don’t have to FEEL. it doesn’t mean those 3 years meant nothing. it just means he handles pain differently.

They are not replacing you. There are no replaceable people. They are trying an easier relationship with someone that they really don't know.
Remember that you value depends only on how you see yourself. You deserve better
