So I've been separated from my sons dad for 9 years. Hes been in a relationship with a woman for approx 6 years.
I generally have no very little issues with them both. After a very messy break up, we have settled into respectful co parenting but at a distance from each other.
There have always been arguments in the past , always involving money about him not paying maintenance etc. Iv also had to sell the family home because he pressurised me into paying him back his contribution to the initial deposit. (Long story, but basically he places money over his child's wellbeing very often)
However my son is now 18 and since my ex no longer has to contribute financially arguments have stopped.
Over the past 6 years my son used to spend 1 night a week at their house, but this stopped when he reached about 15, as he didnt have his own room there and would have to sleep on a blow up bed in her sons bedroom.
However, a few days ago my ex's girlfriend posted a status and pictures on social media tagging my son in, stating how proud she is to be a mum.
I feel completely uncomfortable with this. I understand she has known him for 6 years, and he has been a part of their lives... but to call herself a mum to him... it just grinds my gears.
I dont really buy in to the whole step mum thing... I'm under no illusion if she and my ex split she would never bother to see my son again.
I feel like she's taking credit for my parenting.... am I over reacting???
