Namechanged for this as it's been eating me up for a while.
Background: I am a single parent to an 8 year old. His Dad has had the same girlfriend for a few years and my child knows her fairly well. They have a child together now. We generally all get along well, meet for coffee, have friendly handovers.
A week or two ago my son did up the catch on my charm bracelet for me as I can't manage it myself, and casually mentioned that last year for Christmas he had got SM -(I am reluctant to call her that but it's apparently what she tells him to call her) - a charm for her similar bracelet. A heart. With 'Mum' on. I choked back all of my butthurt as I recalled the smelly fucking candle I had got from my own son that year and didn't really know what to say. I've never had anything like that from him, and he's MY SON.
Today he dropped into conversation another expensive gift he is going to get her for Christmas this year and my heart just feels like someone has stabbed it.
Especially as they are apparently perpetually broke and I have lent them (and never seen a penny of) a lot of money this year that I can scarcely afford myself but felt sorry for them when they complained about being short.
I don't really have anyone who can take my boy shopping to buy me lavish gifts (with my own money) but I was thinking of just handing him £50 and begging a friend or my Nan or someone to take him out for an hour just so I have something to open on Christmas Day - as it's just me and him this year and it would be nice to feel special, especially now I know where the goalposts are.
I don't know whether to say something about the Mum pendant and risk spoiling our great dynamic, because we do have a great relationship, or to just swallow it.
AIBU?
