Does anybody understand what I'm doing wrong?

I have aspergers and I'm not very popular with the woman. I keep on meeting girls and everytime I ask them. If they'd like to be friends. They say no I'm sorry I've got a boyfriend. I'm sorry I'm a single mum and I've just got out of a bad relationship. Also sometimes they say I'm sorry I can't be friends with you because I work for the company you're supported by. I'm supported by National Autistic Society. Who supports people on the Autistic Spectrum. All of these girls saying no are staff. The other day I was working with a nice young girl who was also looking. I had a good time working with her. I've never met her before. She was completely new to me. At the end of the day I told her that I'd had a lot of fun with you and that hopefully I will see you again sometime and she said I would like to see you again. I asked herwhen she's likely to be coming to the company that supports me again. She said I'll probably see her quite a lot because the companies short staffed. I also asked her out for a coffee and she said she'll have a chat with my support team. To find out if I need extra support with socialising. The last thing she said was you come across as very confidence and most girls would love being Friends with you. Is there any way I can get passed all these boundaries and harshness. I'm 36 and most of the staff on my support team are too strict with. Mostly all of them are girls as well
