It doesn't make me feel insecure or jealous, I just don't like rude people
Okay, so let’s break it down.
Fast forward to yesterday and she knocks, I answer, she asks me if DH "lives here?"
What’s the problem with this? If you‘ve only met her once before, several years ago, she probably isn’t going to remember you and was double checking she had the right address.
so she again cuts me out and speaks to him as if they're alone.
Or it’s just that she saw she had the right address and had found the right person so conversed with them over the matter at hand.
She didn’t refuse to acknowledge you. She didn’t ignore you. She just didn’t have anything more to say to you.
she comes over the road completely ignoring my presence yet again, coo's over our baby asking my DH all about "his" baby as if he's a single parent.
It is his baby. Just as it’s your baby. Being his baby doesn’t also stop it being your baby. You are oversensitive here.
I butted in a few times with normal conversation but I'm starting to think I should outright ask women like her if they can see me!?
Butting in is rude behaviour from you. She doesn’t know you, you’ve only met once, and in this climate not hanging around for too much social chit chat is best.
You don’t have to be involved in every conversation your partner is. He is allowed his own friendships and relationships with others without your input.
I stand by my initial assessment and really can’t see that she did anything wrong or was being rude at all. It’s all in your head.
