How do I get through this? 😭

Hi all,

So I posted a few days ago about my situation - me and ex partner broke up after 15 years, he moved on within days, came back & we tried working things out & he then did the exact same thing. Ive never felt so worthless.

He's already sleeping with & seeing the girl (she's 24 he's 33) he was texting and which evidently caused the breakup and to be honest, she's so much better than I could hope to be! Shes blonde, very pretty, has her own house & works the same job as my partner (they're both prison officers)

My ex doesn't give a damn about me, he messed me up pretty bad (see post "should I destroy my ex partner's life as he's destroyed mine"), I'm having to pay for counselling and ive resorted to anti-depressants because I'm the lowest ive ever felt & I've been desperate for the pain to stop.

I can't get over this, I invested so much time. He's landed on his feet & nothing has changed for him, meanwhile my whole world is upside down & I'm having to start from scratch at the age of 32. Ive always wanted children desperately, I'm terrified I'm not going to meet anyone and that I won't get what I want out of life. He's acting like we dated for a few days, 15 years and ive never witnessed anything like this. Im really struggling to cope.

Any advice/help would be appreciated right now. I'm at the end of my tether 😫😓
