My ex and I were in an 10 month relationship which ended in October last year after he ghosted me. At the time it was horrendous, we'd started as friends (knew each other at uni- years ago but had stayed in sporadic contact, we were never romantically involved before). I confided in him about a previous abusive relationship which I was having therapy for and although I felt no attraction to him at first we ended up getting together and things were amazing. I'd never felt this way before, he promised me the earth, told me how he would do anything for me, he'd never hurt me etc. Our mutual friends from uni all said what a nice, genuine guy he was and I let my guard down.
It starting going a bit off when he wanted to meet my DD (age 4), after about 3 months of dating. I didn't think it was right as 3 months was still quite early but when I told him this he was really sulky and off with me. We only ever saw each other when DD was with her dad (we are on good terms) but we spoke on the phone daily and had spoken about marriage and kids.
Anyway one morning in October I wake up from a text saying "sorry, can't do this anymore. Never meant to hurt you." That was it. No explanation, no apologies. Just silence. It really broke me. How could I be such an awful judge of character?! How could he treat me like this knowing about my past and what I had been through? I've heard through the grapevine he is trying again with his ex, part of me wants to believe he was single when we got together- everyone we knew mutually thought he was but to be honest I can't believe anything that comes out of his mouth. Have I been the OW?! He told me how he fell out of love with his ex after they had kids (he has a 4yo and 8yo) and they split because she'd cheated on him.
It's taken me until now to start feeling better, my self esteem is still on existent. I haven't seen him at all since October- mysteriously he vanished into thin air (!) but this week I found out he has applied for a job in the same company I work in. Not only that, a job in my department. I can't work with him, I don't trust him and we'd have to work in a team if he got the job. There's no bloody way I even want to look at his face again. I'm not a violent person but I keep fantasising about ways to torture him (being tongue in cheek here!)
What do I do? My sister thinks I should talk to HR but I feel that will make me look childish and like I am demanding my own way. The brazen part of me thinks I should just brazen it out and if he gets teller job, learn how to live with it but there are still days when I randomly burst into tears. I feel like I was just starting to feel better and now he's somehow violating my work life.
