IT RUNS IN THE FAMILY.
When I lived at home, my mother couldn't fall asleep until she heard the sound of my key.
My grandmother still can't take the fact that our family members go on holidays or have to stay at hospitals at times. She's fine when you don't call for 2 weeks, but once you tell her you're about to head for the capitol for the weekend / get your wisdom teeth removed she goes insane.

Now, I always considered this ridiculous, but I fear I'm becoming them.
I'm worrying about my boyfriend all of the time. It's not that it's showing, I try to hide it, but it fucks with my head really pretty much.
F.e.: Tonight he's working, he works at the doors of some small, nice, alternative club and he won't be home before 4 a.m. The thing is, he WALKS home; a walk I'd tend to avoid (it's a rather big city); I'd take a taxi instead.
But no, he got no safety issues at all. He enjoys walking around downtown in the dark. And I hate it. I expect myself lying awake until he calls me in the morning. I'm my mother

What do I do?
Anyone else going through this?

nothing you can do. I'd be worried too, but taxis cost money.. and if he'd rather save the cash, then let him walk home. Maybe explain to him how much you worry about him and his safety without appearing too fanatical, something along the lines of "I know you like to walk home at night, but I get really worried that something will happen, can you give me a call or a text message when you get home so I know you're ok?"

We've been through that, it's something he understands ... I mean he texts me regularly on nights like these.
Thing is, he got beaten up before... by strangers, out of the blue, for no reason. Weird story, he was with his ex then, it happened years ago, at like 3 p.m. in full daylight, in a central spot. So, I know it's important for him to "walk the dark", I think for him it's part of fighting his own fears/memories and so on.
Maybe this enhances my worries.

I don't know. I just wish I could protect him and protect him from all evil, but then again he's 28 and I'm not his mother.

Aaargh.
