Yes. A lot of people have taken advantage of me and I usually put up a block unless I'm really connected with that person and even then they kinda have to work a lot for me to open up. I just don't like feeling vulnerable
I get so nervous and it's very telly since I try to avoid the visual contact (I'm talking about when you're expressing someone that you like it)
That's something I've tried to get better but I just keep getting nervous, the fear of not being liked in the same way by that other person is what gets me this way.
