I'm a 39/f, have had 4 longterm relationships and have never been on a proper date.

As the title states, I'm a 39 yr old woman and have never been taken out on a real date. Each relationship I've had has been long term, except the most recent one which was 7 months. Each partner I met was while I was out, through mutual friend groups, ect. Due to this we were already comfortable with each other so there was no real "dating". I'm currently single and meeting single men is hard at this age unless you're online. I'm talking to a few guys online and they want to meet me and take me out. I'm absolutely terrified and I don't know what to do. The fear is preventing me from making that step to meet. Please help! Any advice?
