Divorce

[Ginno19]

So after 5 months of marriage I have decided enough is enough .
B4 we wes i had a 10 year old and 18 year old .
She had 28 and 30 year old , both with partners .
Anyway shorty after marriage I asked W to co.e swimming with me and my youngest ( 11) to her reply was " no...I've done my child thing with my own "( red flag)
Then her daughter had a new born which I was delighted 4 , but her daughters bloke was. Ever around and always here or there. This made my wife having to go and help her daughter with up bring of newborn . I was OK with this at 1st but I never got any calls or text about when she would be back home .
7 weeks this lasted then after a few conversations ibe decided to leave but she now blames me for not taking her daughters side

Doesn’t sound as though it’s working out for either of you. Such a short marriage should be straightforward to end depending on financial and housing entanglements.

As to who is being unreasonable that needs more context. You are both responsible for your own children and will naturally prioritise them. She doesn’t have to parent your younger ones and you need to accept she will want to support her daughter.
