advice on ending relationship

[BERKSDAD1983]

Hi all,

i've been here before asking for advice.
but now i think it is time my partner and i maybe calling it a day.
we have a 4 month old baby together, and last year i got in on the mortgage. she also has an 8 year old living with us.

how do we go about making this an amicable split?

So it was her house before you got together?
And she will be looking after 2 kids?
If that is the case then I suggest you move out and find somewhere else to live.
Have you been paying the mortgage?
And if so for how long in comparison to how long she would have been paying it?
Have you had counselling together to see if you can overcome any issues you have?
Why do you think it's best to separate?

at the moment i dont care about the house or where i'd' go (i do have parents not far however).

we continue to have arguments, she thinks i keep her in a bubble but not introducing her properly to friends - i only have two close friends. in 2.5 years they've met a handful of times. im not really a social person. im quite introvert.
she has history with her ex who put her into a lot of debt which he still carries, she doesnt anymore since i got on mortgage and owned house - seperating their financial ties.
she found a credit card statement which i never told her about, it was only £150, and late £5 payment. i dont have issues with money, have a good joib - just forgot at the time as we had garage conversion going on so busy time.
she felt that was me keeping major secret, and fear of financial debt when through her mind.
But it isnt just that - she is very anxious in my opinion - she reads too much into what people say, she goes from 1+1 = 3. and everyone is then always wrong but her. and usually its because of something my family have said.....its beginning to be a chore to manage that anxiety.
she is also very hot headed, she goes to hot too quick and doesnt talk to me, but at me. i actually feel very belittled at times.

If you are absolutely sure and don’t want to work at the relationship/try counselling , then i’d Say “this isn’t working for me anymore , I will always care for you as the mother of my child but think that we are better apart”
Don’t give her lots of examples of what you deem as failings as this will seem as if you’re blaming her for the break up when the reality seems like you’re not compatible and I would say this if she asks you for a specific reason.
I would make it clear to her , you want no claim on her house (as I think that’s what you’ve indicated in your post? that it’s her house and you’re not worried about it) as she may be concerned about this. I’d contact the mortgage provider with her about removing your name from the deeds and mortgage (assuming that’s your desire) .
Agree together on child care allowance and also a child care schedule between you both. It probably makes sense for you to move back to your parents and look for a place to live as soon as possible as living together will make it harder for her to process the information and start to move on.

She does appear to be difficult.

Get your legal position checked before you do anything rash
