I met my gf at  a friend's party, I was working and at University part time and due to finish my degree the the following year. I am 39 and she is 33. She wasn't working then and but now is currently works 9hours a week.

She told me the first time we met that she had two children girls, one aged 7 and the other aged 3 then. She was really honest and upfront, in addition I really liked the girl so I gave it to. I have two kids (boys) of my own with my ex of 10years aged 12 and 16. I single handedly raised the cars by myself till 3 years ago wen sister asked if she could adopt them so it would give me a chance to achieve some sort of career iny life, as I spend the last 13years prior looking after my boys as a single parent.

 I explained to her that I wanted to spend time with her alone first so we got to know each other. We had booked a caravan weekend in Camber sands but to my surprise when I went to pick her up she had the kids with her bearing in mind this was our third time together. She said she couldn't get a babysitter, which I was pissed off with, she could have cancelled I wouldn't have minded. Ended spending the weekend with her children.
Things moved pretty quickly after, if I asked for time together she would say well the kids know you already so there is no point. To distance myself from her I decided to see her every fortnight which worked well.

She meets my boys once month. And to be honest they are well behaved. One just passed his GCSE and looking forward to his A levels.

We spoke about her children and the possibility of having more in the future. I made it clear to her that I was happy in the relationship but was not ready to move in or have anymore children as I wanted a couple of years to finish Uni, and get a but of experience plus good job before settling. She was ok with this, she said she wanted to focus on her kids so they be a bit older before we settled together.
I finished Uni and got a good paying job, bought myself a new car something I had never done before. We kept seeing each other every fortnight and the odd weekend away the first year. She lives 30 miles away
Fast forward 2 years later we had booked a holiday to Disneyland Paris however this got cancelled 3 days before departure due to the Covid19.
The country went into lockdown when I was at hers preparing for our flights. She asked me to stay at hers as I was fourloghed and so was she, she said she would have struggled with two kids, plus she don't drive and leaves in a village. I agreed out of love.
We had agreed not to have children before so she had cool fitted. However during lockdown she kept claiming she had thrush and believed it was the coil so she had it removed and went back on the pill.

A month or so later to my surprise she said she had missed her period. We done a test and came back pregnant, I was in shock and still in shock. She wants to keep the baby but I am not ready to be dad yet. I only been doing my job for 8 months. And doing further training on PLC programming and software development which I am going to complete next year.

She wants me to swap my car for a five door, wants me roive in and wants to be a stay at home parent. This will mean leaving my current job and being the bread winner in the family. I am not ready for that, and I currently resent her kids 
I know it's too late now and the baby is on its way but I am confused.
Also I didn't know how fully bad her skids were till we were in lockdown. They slam doors, call their mum stupid idiot which infuriates me. Also we don't watch TV in the front room as the kids will go ballistic if we changed the channel, so I end up watching telly in the bedroom even though I bought them a telly each for their rooms including the one in the front room.

Skids don't eat fruits or veggies at all, they eat snacks. If they refuse to eat dinner they will just say we don't want it, then go straight to the fridge and get ice cream.

When they do miss behave she says sort them out, when I try to they say why don't you just leave and go back to your house, she just says that's not a nice thing to say to him, and nothing else. I feel like she wants to be with me for what I can provide. The youngest child will ask me to play with her which I do but when I get tired and say no maybe tomoro she will throw a tantrum as if I am not allowed time off, she has hit me on several occasions for saying no not today. We have no privacy when I am there, the girls just walk in and out of the bedroom. The 9 year old walked on me naked once, mysmy gfjgf laugh about it, we share the bed with the 5year old I find this wierd we have spoken about it and she says they just want cuddles  

The kids don't have a routine in fact I go to bed earlier than they do, I have raised this with her she just says they are kids. But I was brought up differently. 

They spend the whole dayaday watching TV and take the tablets to bed, and there is no time limits on these. I dont mind someresponsibility for her children, I am happy to be thier stepdad but I am not their dad, when i told her this she started crying saying all they want is love from me, which I get but I am not the father. I will take on the role of being a parent to them with limitations Both kids don't see thier dad due to her reasons. I realized who she really is during this time that my mind is telling me to leave her, baby or no baby. My children are old enough now I don't want to go thru all that again  with someone else's kids.

The baby in due in February next year. I can either move in with her but I don't see this working, I am very ambitious and want to achieve as she is not bothered. Or I can just walk away now. I dont mind paying Cs than to live with that horror. I think I will end up with depression
