The relationship is serious.
You say this twice, so you clearly believe it.
Unfortunately, your b/f doesn't.
He is far more serious about not upsetting an ex - who has been an ex for 3 years!
so now when we are both at home and he has his som with nothing to do we can’t meet up , not even to the play ground
Do you find it difficult to fancy such a wet lettuce of a man?
I would, but the larger issue would be that he is not taking full responsibility for his relationship with his son. He is acting as if he - a father ffs - has no autonomy in decisions concerning his child.
his son mentioned my daughter a few times to his ex and she went absolutely ballistic and has banned my partner from bringing his son around me
😂😂😂
She's not allowed to "ban" her child from seeing anybody the child's father deems fit.
Why is he pandering to her?
You will have bigger problems than the ostensible child issue with this guy. He's not a full adult, he allows somebody else to dictate how he leads his life. This mentality (to be clear HIS, not the ex's) is going to cause larger & larger problems in your relationship.
However, he doesn’t want to rock the boat with his ex as she was quite abusive to him in the past and gets angry quickly
Aaaaw, poor ickle manbaby.
Again - how can you get it on with such a feeble guy?
He's either bullshitting you with the detestable MyCrazyEx trope, just to have an easy life.
Or he's correct, his ex is controlling, but he is a pushover who allows the thought of his ex being angry about his personal parenting decisions to be more important to him than having an honest, healthy & inclusive relationship with you.
Neither of those scenarios are attractive, are they?
Think of the thousands of threads on MN started by women who have escaped from seriously abusive relationships. Most of them don't allow their ex - who is often now indulging himself in post-separation abuse by using the kids as pawns - to dictate what happens on THEIR parenting watch.
So why are you tolerating it from this guy?
Your b/f has 50/50. He is equally in charge of his child as his ex is.
Why is he allowing his EX to control his current love life, his relationship with his son, & who his son associates with?
I'd tell him how unattractive his moral cowardice is, & ditch him if he didn't shape up pronto. You might not want to do that - but seriously - are you going to keep playing second fiddle & be treated like a dirty secret, because your b/f doesn't have the balls to parent his child like the adult he is? Let alone the total disrespect to you ...
Sorry OP - no solutions, just lay it on the line/LTB to offer. You are worth more than this feebleness, it's deeply unattractive & insulting.
