I need to end this....

[Notsleptin2wholegoddamnyears]

I have been with my OH for 4.5yrs, 2.5yr old son together and currently 6wks pregnant with my second.
History of the relationship is far from good, OH seems to have major issues regarding telling the truth, 100’s of lies, he never confesses to lying, I don’t know what the truth is anymore, he’s been manipulative, volatile, emotionally abusive and i think I’m done.
He betrayed my trust again at the weekend, I don’t trust him, i never will, he will never change despite his promises every time he gets caught out.
I’m so so scared to end it, I work, have a toddler, a dog and a baby on the way. I have debt and a mortgage, nursery fees.
I’m scared of fucking up my kids lives, or my beautiful innocent son asking me where daddy has gone.
I feel incredible guilt for wanting out of the relationship.....he had done this but ultimately it is my decision to break up the family.
How do you move past the guilt???
Im so hurt and confused.

Do you need help in making a decision regarding your current pregnancy.
At 6 weeks you still have options.

Look, he's abusive and a liar and untrustworthy.
You know what you need to do.

Is it your house?
Is the mortgage in your name only?

The pregnancy is up in the air anyway, I have been bleeding for over a week now, I have a second scan on Monday which will give me a clearer picture of what is going on. I’m already tied to this man for the rest of my life with my son, I don’t know how I would feel about terminating the pregnancy, it’s not something I have considered......

The house is in my name, everything is in my name due to his bad credit but he paid the deposit for the hous in full, with some inheritance.
I have another property that I intend to sell which would pay him back what he has put into the house.
He would walk away with a lot of money is his back pocket, no debt, no overheads and be able to nicely set himself up.......I would be left with all the shit and skint.

I have also never spent a night away from my son, this terrifies me. His relationship with his dad is not the best, my son is very young but appears to be quite clued up about his dad and appears to keep him at arms length, he is not comfortable being alone with him, my OH just eminates anger and frustration and I’m adamant the little one is wary of this.
