How to get through this?

[Teaandcakeat8]

My ex dp and I split after 2 years in late December. We worked together in a fairly small office. The split was looking to be pretty amicable.

He's just started dating a girl 8 years his junior who works in our office. I have to see them every day and it's tearing my apart. I can't leave my job as I've just bought a house and there are few jobs coming up in the area (so can't move).

How can I get through this? I think I'm doing ok then this evening I see he's removed all traces of me from his social media and her the same. I feel like the whole relationship meant nothing as he's moved on 6 weeks later.

What can I do? My confidence is at rock bottom and I know I'll never be happy again.

Don't talk about either of them at work unless it's in an essential & purely professional capacity; even then keep it as brief as possible.
Rise above this & move on - you will quickly become uninteresting to the gossips & watchers if you don't put on a show for them.
Whatever your ex & his current gf get up to out of work is not your problem & not your business; the same applies vice versa.
YOU are the professional here, you can use the unfortunate event to your benefit - build up your reputation by doing what you are paid to do, to the highest of standards.
