Apologies that this is long, trying to avoid drip feed. Namechanged also.
I have two close friends who I’ve known for many years. We had our dcs (2 each) at around the same time and would spend lots LOADS of time together.
Been through a lot such as friend one losing her Mum, friend two going through an awful late mc and her marriage broke down. My own marriage ended too.
Anyway both friends are now in a happy place, great dh’s, children grown and flown the nest (as have mine) I however now have a 4yo ds with my current dp.
This has meant that I haven’t been able to see them as much (they still spend lots of time together) as dp and I work hours around each other as we can’t afford childcare, no family to help etc.
I do try to meet up with them though as I love them dearly and enjoy seeing them but I feel that my circumstances mean that we’ve ‘drifted’ somewhat (or maybe just that I’ve ‘drifted’ due to horrid pnd, exhausted as ds isn’t the easiest, I don’t know)
Anyway, last month we all met up at friend one’s house for drinks, I was so excited to be having an evening ‘off’ and I hadn’t seen either of them for about 6 months.
The evening was odd. Friend two isn’t as well off as friend one but appears to be trying to copy her. She took great pleasure telling me that she has the same rediculously expensive kitchenware and has taken out finance on a flashy car very similar to friend one’s etc. I’m NOT jealous, my car is flashy enough 
and I’ve no interest in kitchen stuff. But knowing her circumstances, friend two must be getting into debt to fund her current lifestyle whereas friend one has been very successful and can comfortably afford hers.
Later on, I went to the toilet and on my way back I heard them laughing in the kitchen, muttering in a bitchy way. I’ve known them a long time, I know that’s what they were doing.
I walked into the kitchen expecting to be included in the conversation but instead they quickly changed the subject to food and shot each other a ‘look’ 
We had all previously been talking about our respective lives and having a moan about our oh’s and a laugh about our dc’s etc so I’m wondering if (helped by booze) I’ve said something that they then had a bitch about while they thought I couldn’t hear them.
It upset me so I made an excuse about being tired and got a taxi home, I’d been there a few hours so hopefully it didn’t look rude and I smiled and pretended to be okay.
Friend one hasn’t been in touch since though so maybe she does think I was rude. She’s usually the type to text ‘you okay?’ rather than take offence though.
I wouldn’t think anything of her not messaging me except she invited my 2 adult dc to a bbq but not me, my dp or our ds.
I think this is possibly pass/agg as I know that’s how she’s been with others in the past (but never me, we’re ‘close friends’ )
Friend two has since messaged asking if she could come and see me but I said I was ‘busy’ that day because I just feel awkward about her now. She’s messaged me again to say we must catch up soon.
These are the only two real friends that I still have, I have acquaintances who I’m friendly with but nobody who I’m as close to as them.
My dp thinks it’s just because we’re at different places in our lives atm and I’m just naturally more busy than them and that I seem to be paranoid overthinking.
I think my dp is just trying to be kind. Friend one has never invited my dc’s but not me, until now.
AIBU to think that they’re not really my friends anymore?
