I think it depends on you, the ex, and the relationship/how it ended. In my case, I am more than happy to not talk to any of my exes again, and I'm sure it's the same for them! Sometimes moving on is the best thing you can do for everyone.
Was it a toxic relationship? If not, then sure, talk to them.
Was it a bad breakup? If not, then sure, talk to them.
Are you both over each other? If not, then probably should avoid talking to them until both people have moved on.
I'm on good terms with all my exes which I know isn't the norm but it's possible in the right circumstances.
No
if you love her talk
I think it's a good thing to become friends w her
depends on how things ended between you and the ex
i think exes can remain friends or acquaintances as long as there’s boundaries and mutual respect
If you hurt them or did wrong start with apologizing it can go a long way. But only if you mean it.
can be if they’re not toxic.
Nope there a ex for a reason
If you ended on good terms it's not a bad idea
