I have a handful of friends who I've known for 15 years plus.
I'm not particularly extrovert and don't feel the need to make new friends. It's hard enough finding time for the friends I do have. I'm not averse to making new friends and will happily speak to anyone, but rarely do I meet anyone nowadays that I want to pursue an actual friendship with.
I met someone through work a couple of years ago. She is much younger than me and during this time, they found out they were pregnant (and were not in a long term relationship). I took her under my wing a bit and gave her some support, having been through similar. I visited her and her newborn baby, went to the christening etc. It was a big effort for me tbh as doing social events with people I don't know very well is not really my cup of tea. I could see she had some good friends around her that were also supportive.
We have since both left this workplace. She has got in touch recently to say she'd love to meet. I feel really selfish for feeling like this but...I don't feel particularly inclined to meet her. Nothing against her, but I don't feel we particularly click or anything to strike up a proper friendship. I'm quite precious of my spare time and would rather use it to meet one of my other friends. It would be different if she was having a tough time and really needed my help - but I don't think this is the case. So I don't see the point really. Am I a being a cold hearted bitch?!!
