I have a colleague who I was ‘friends’ with or at least I thought I was for many years. Just before I went on mat leave my whole team who I had worked with for a decade left to go another company. She left without saying a word to me and instead other colleagues who I was less friendly with kept me updated on what was happening, which I appreciated. I contacted her once after that to check how she was doing but she never reached out to me throughout my mat leave or after I returned to work (to a team which obviously looked completely different to what I had been used to) to check if I was doing ok. Anyway now that I’ve changed jobs and work for a client she suddenly wants to keep in touch and I don’t really feel like it. I’ve tried to make it clear by being polite and professional in emails but not really engaging with requests to meet up but she’s quite persistent. I know she’s very good at being ‘friendly’ when she needs to be and I don’t want to get sucked into that with someone who I feel is only interested now there’s a business reason.
