Okay so basically, I see my girlfriend 4 times a week.
But every so often I'm faced with my girlfriend texting me to say;

'Hey, my friend invited me to a girly party and I really want to go, can I see you a different day?'

I always say 'Sure, go ahead'.

The problem I would have with this is that it's such short notice, like 1 day in advance. I want to see her, I planned to see her. I'm not going out with my friends because I was expecting to see her.

I used to get a bit sulky about this, which helped nothing.

Nowadays I tell her it's fine but then let the texting die and initiate a soft next.
I'll usually text back the next day.

What's the best way to deal with this? She's not flaking on me, just changing out plans at short notice. How would you guys deal with it?

Thanks!

Sounds like a girl you don't live with? If I'm right you date her four times a week as it is, do you have nothing else to do?

I honestly think you'd do well to focus on doing a ton of other stuff in your life, if your girlfriend letting you know she was seeing her friends made you sulky, sounds like she has too much emotional power over you.

Lockdown is spot on. 4 times a week? Do you really have nothing better to do?

It's one thing to like someone, or be in love with them. But nobody is joined at the hip, every day, forever. Healthy relationships have time for other things. It also helps you appreciate the time you do have with her.

The soft next is a good response if the short notice thing is a problem, but I surely hope when it happens you aren't just sitting around biting your nails.

No of course I don't sit around.

Whenever she arranges to go to a party, I also arrange to go out.

It's simple.

I'm not sure what the best way to deal with it is.
I kinda wanna let her no that it's not cool. But there's no way I'm going to do that unless I can find away that doesn't sound at all needy.

I´m sure she loves the attention and all but I would perhaps priorities other happenings in your life that fill up your time. so much so that you wont always manage 4 times a week. "Sweetheart, My buddies need me and have insisted on kidnapping me tomorrow!"

when she comments your message them say something along the lines of "Just means next time will be twice as fun "

You dont have to make excuses for living an interesting life, shes gonna love you more for it!!
