My partner has left me at 12 weeks pregnant

[Jasmine01]

Please can someone help me with advice?
My partner has just left me at 12 weeks pregnant (first scan due next week). We have been together almost 3 years. He has 2 kids from previous. One who is 9yr old girl and he says that she is missing him desperately as she lives with her mum.
He works 2 jobs to support his other kids plus my daughter age 8.
He's decided that he needs to be there for his daughter and can't be with me at the same time as it will cause arguments due to lack of seeing each other.
I'm totally heartbroken that he's chosen to leave me while pregnant to be with his daughter who he reckons is depressed due to lack of seeing him. He doesn't see that he is destroying me and walking out on this unborn baby. It's like he just doesn't care anymore. It was his suggestion to have this baby too.
I just don't know what to do as I don't want to go through this pregnancy on my own nor do I want to have to go through sleepless nights with a newnorn etc. I just don't know how I can do it with 2 jobs myself and a 8yr old daughter.
Can anyone offer any reassuring advice please? 😢

Have you been to your scan now, op?

No I cancelled my scan. It was for tomorrow..I still haven't made a decision on what to do about the baby

It was a pleasure, Jasmine01. Happy to help.

I'm imagining you've come to a decision now. I wish you all the very best in whichever path you've chosen.

He says that I will never understand the pain he's going through at doing this to me or that I will understand his sacrifice.

He's so noble, isn't he? Not buggering off because he doesn't fancy the idea of stepping up to the responsibility of a baby, oh no. This prince among men is sacrificing his own happiness and putting his other child's needs above his own. Honest.

OP, you're on your own as far as any commitment from him is concerned. The question you need to ask yourself is: can you do the single mother gig? And can you do it with the possibility of this arsewipe popping in and out of your life at will? This is a decision not just for this week but for the next 18 years, at least.

Please don't let him off scot free for all this trouble.
He is a coward, and should you decide to have this baby, it is do-able with your other DD.
The school run with a new born is not the epic thing everyone makes it out to be... I would drop my child off, and watch her walk into reception. Then you just use the pram at home time.
Please do make him pay towards this child... He wanted.... As otherwise you are making your eldest suffer financially by stretching your money three ways...
This is not out of spite, just a case of he should pay from molar reasons.
