If you think it is, the problem is you.

What if you're only forcing people to invite you out of kindness and not because they honestly wanted to invite you in the first place?   
Or that you don't matter enough to be invited first? 

You don't have to be the main character of someone's else life, but you may want to be something else than background somedays.

I believe that most people should be able to tell when they're being welcomed or just being tolerated. If you think you need to 'matter enough', then you're just being entitled. Contrary to what you might think, not being invited doesn't always mean you're not welcome. Sometimes it does, but not always. 

Think about it like this. Most events have one person as their main driving force – the archetypal "organizer." It is just simply and sheerly unfair and entitled to expect that person to remember every single friend of theirs and always invite them to every event. 

If you don't ask, you won't know. If you do ask, you'll know. Only knowing is a positive outcome.
