Had a child with my ex. Started having doubts about my daughter being mine biologically. We lived together for the first two years of her life and another 2 years separated in a share custody agreement without any court order.

Never been married.

About 3 days ago i got test results that actually she’s not mine.

Can i be held accountable for anything in this case if i decide to leave? Does my ex have any type of entitlement to my finances or anything else?

Any help is appreciated

EDIT: For those who are wondering why I am thinking of leaving.

That kid is everything to me. I really wanted kids, made bunch of mistakes, but never ever let her down or anything.

Her mom on the other hand makes my life so difficult, that it pushes me away.

She’s vindictive and anything i never enough. I do 12 hour shifts 5 days a week. So i work about 20 hours more than her. I had to be the guarantor for her to secure the flat.

I get back home at about midnight. Have to wake up at 6 am, travel to hers, to get our daughter ready for nursery, because her mom works 7am-3pm and nursery is at 8am. By the time i drop her off, i need to get myself ready for work at 11 am.

Every single time she needs a day off or something comes up and i am not able to look after the kid because i made plans, she always wants to ship her off to her friends who i don’t, so i cancel my plans and bend over backwards to look after our daughter while she does whatever she does. Company nights out, i want to get my nails done, i’m on my period(real excuse) and etc.

The company i work for is very family oriented, so they help out a lot. Staff members are willing to swap shifts or cover me, anything related to childcare.

When i ask for her to take care of out daughter, for me to get those 8 hours of sleep or something or i want to go or do something, I’m met with, oh i cant nobody wants to swap shifts with me or a constant eye roll.

When she needs money, if i question why, i get “don’t ask stupid questions, when i ask you have to transfer money”

Blames me for everything. She can’t maintain a relationship - my fault, not having enough money - my fault, mental health - my fault.

Talking about how she can’t wait till our daughter turns 16 so she could be free from the responsibility and go travelling.

A bit of a rant
