Invite Discrepancy

Hey ladies,
I always make to any function/celebration if I'm invited, I try my best to attend , if can't make it I will visit later with gift.
If I'm invited thru my dad's/mom's/siblings / husband's friends, if I Know them personally well like an aquitance , I attend the function for formality and return soon.

Now, in US - I'm attending bdays/ other parties mostly thru my husband's friends/collegues. Sometimes I don't go because I have never met them, don't know them. I know a family very well , they exctracted so much help when they moved to my place from other state.
Quite often the lady usually calls , text and come to my house monthly once , twice since she is new to the place. Kind of aquitances not a friend.
They have a party at home, for which they sent evite to my DH. She didn't call or text about the party. It's not a kid's birthday party.
Whenever we have Pooja/party/potlucks at my place, I invite thru calls, send reminder texts along with evite.
I find this is weird, when they need help they call , come home but now not even a text message.
Should I go attend the party or not?
DH says your wish.
Ps.
I personally feel the person should be mature mannered enough to call/ send evite to me. She has all my contacts info checks my fb, insta, Whatsapp things.

 

She didn't text also... Basically no information from her side. Her husband sent evite to my dh.
Thank you for idea on "going out "

 

The problem I had mentioned clearly on my opening post.
She didn't bother to mention, she visited my house on some need last week too. But didn't mention anything about party. When she wants something to be done, pick up drop would call 100 times. , when they are in need time, distance, money are not constraint. But when it comes to them no respect to inform. That's the problem hope it's clear now for you

 

that's our mistake. We give more respect /importance to underserving people.
