I used to be part of a support group and I met a few people through this. I met a person here and initially we hit it off. However I started to be put off by their behaviour towards me and from my point of view the relationship has soured and I no longer like them.
Behaviour includes questing my professional knowledge and qualifications, looking at my social media and asking why they were not invited to meet up with x and y, being patronising towards me in front of other members of the support group (I stood up to them over this and they did apologise) and talking about their problems non-stop. It just all got too much and I have reduced contact, however they still contact me and I don't always reply.
They have invited me to an event for them that I cannot attend as I am busy. They replied that they still want to meet me one-on-one. Obviously I don't want to because I find them very draining.
I know that they have severe social anxiety so I'm not sure how to approach this. They tend to press you for an explaination and I want to avoid this.
Any advice welcome, I feel a bit stuck.
