Friend of many years invited to wedding...

Can you talk to the friend in private? He may not even be aware of what she is up to. Even if he is, that is highly disrespectful and should not be tolerated because she is not mature enough to be in a relationship. Hopefully you and him can work this out.

I am SO SO sorry you have to deal with this. I honestly have no advice. I've been in this situation before, not with sending a wedding invite, just simply being friends with a boy who's got a girlfriend who sees every women as a threat to her.

Unfortunately, a lot of the time the boy is aware when their girlfriend's act like this and just let them get away with it to keep the relationship. It doesn't matter if their friend is hurt by it.

The only advice I can give you, and that I had to take myself when in this situation was to let the friend go, if they were going to let their SO ruin our friendship, then they have decided how important you are to them. I was told I couldn't hang out with my BEST FRIEND without his girlfriend being there by her, he obliged by it, so I stopped hanging out all together because he was someone I would hang out with every day just the two of us, if his girlfriend couldn't be present for whatever reason we were not allowed to hang out.

When FH and I started dating, he was so willing to tell one of his girl best friends they couldn't hang out any more, and I made it a point that he could still be friends with her and that I trusted him. She did end up doing some shady ishhh and disrespected our relationship, but he was honest about it and stopped hanging out with her after that, all on his own. I never told him who he could and couldn't hang out with.

Girls who do this are insecure in their relationships, so hold your head up high, and don't let her get to you, I will assure you this is 100% not about you and 100% about her not trusting her boyfriend!

I've had to deal with TWO girls like this in the past. I was in a happy relationship at the time, and had no intentions of taking their bfs because they were just good friends.
Those girls are just very controlling and feel insecure.
Do NOT let her get to you. If see gets to you then she has something to be proud of herself for no reason at all lol.
If it does concern you a lot though then I would say bring it up to him just like what Michelle said. If he was your friend then he would understand. If not then he is just blinded by love. I'm sure he will come around though if he starts to see it later.

Oof, that doesn't sound like a fun position to be in at ALL! I haven't been there myself, but my sister was until recently. One of her best guy friends was with a girl who didn't want him to hang out with any females, regardless of if she was present or not. That also extended to talking to them at all - in person, on the phone, any sort of social media messenger, etc. The girl had been cheated on before so was basically just freaking out. The guy didn't want to "make her" lose trust in him, so he respected her wishes. He even worked with my sister at the time, but my sister only found out what was going on because that dude told another guy in their friend group who in turn told my sister so she would know what was going on. She honestly thought it was the dumbest thing she'd ever heard since the guy was like a brother to her, but took his lead and respected the wishes of the girl. She only ever contacted him on a couple occasions to see if he could cover a shift, and the texts were strictly work-related. The couple broke up about 6 months ago and the dude and my sister picked up their friendship with no hard feelings.

It for sure sucks when it's someone that close to you, but hold your head high and don't let that chica ruin your happiness. She doesn't deserve that "win". You've got your own good and healthy relationship with a person you love so much that you're about to promise to spend the rest of your life with them. For one day, who cares what that one jealous female says?
