Hi seekersinking, I know abandonment and betrayal of trust that someone will be around can be really painful. But with ex-friends......ex-partners...........ex-husband........perhaps see it as you working through the people out there to find someone (or more people) really worthy of you.
And if the others have turned their backs it's their loss, they haven't lived up to your expectations not vice versa. They haven't been capable of giving you what you needed/deserved/their backing. And it's good that you've found that out/that they aren't around, meaning you can hang out for someone who is going to be capable of giving you their understanding, their caring...........
And there will be people who are capable of that in this world.
So they haven't abandoned you, they just haven't been able to meet a standard . And you do not want to go just changing your standards, wants, needs without very good reason.
