Two weeks ago now, an ex of mine got in contact with me to say the usual.... That they're sorry for how things ended between us, that they hope I'm doing well and in a better place now and sending their love blahdeblah. I replied back to them and asked how things were with them as it's coming up to almost 10 years since we've last spoken, to be polite and also I was shocked I guess. This ex was incredibly abusive in various ways to me, for context. I just have been wondering these last two weeks on and off, why reach out to me after almost a decade to then not reply back? I have had other exes all contact and they always began a conversation and didn't send a message then vanish, so I feel a bit confused. If you reached out to someone to say sorry for how you treated them, if you were genuine, surely you'd not then vanish when getting a response back? I know people will say exes are exes and it shouldn't matter, and I agree, but I can't help feeling confused why they'd do that?
