Basically, the title says it all. lol

My female friends (who were friends of mine before I met my current gf)
act like they absolutely adore my gf and when her and I get together with them I find myself feeling neglected and ignored by my friends because they're SO FOCUSED on her.

I mean, we'll be sitting at a table at one of the nightclubs that we go to regularly to see live music and they don't talk to her and I.
They only talk to HER!!

The last few times one of them never even made eye contact with me the entire time we were sitting at the table because it's like she had blinders on.

One of the other women once arrived at the club after we did and, when she didn't see my gf (she had gone to the restroom), looked at me and didn't even bother to say, " Hi " to me or wave at me. The first thing out of her mouth was:
" Where's ________? "

I feel like they're being very rude and inconsiderate towards me by focusing only on her and not US!!

Geez, they wouldn't even know her if it wasn't for me!!

I guess my question is:
how can I tactfully point out to my gf that I'm sick and tired of being ignored by these women that used to by MY friends before I met her?!!

Her and I have plans to go out with them again this coming Saturday and now I'm actually dreading going because I know that the same thing is going to happen and I'm going to feel like a, " third wheel ", so to speak.
I'm going to feel like it's basically a, " girls night out " and I'm going to feel totally out of place again because they're so enamored with my gf!!

Help, please.
She's wonderful and I don't want her to break up with me because she has the impression that I can't handle the fact that our women friends just absolutely adore her.

It's so bad sometimes that last Friday night one of them spent a half hour straight talking to my gf without making eye contact with me even once, let alone talking to me.

They never talk to her and I.
They only talk to HER and I'm sick and tired of it. smh

I even got very angry one night after it had happened again.
She tried to reassure me that they weren't going to steal her away from me, but I think it's already happened.

I apologized to her the next morning for my behavior the night before and promised her that I would never get upset over it again.
