My partner announced he was leaving in January, we have a 17 month old (I got pregnant by accident, he wanted me to terminate) he also has three children by his ex wife who I have been step parent to for the last few years. He has had our daughter one night a week since we split, but is now threatening going for 50/50 custody (he has this with his other kids) I am struggling financially, yet to hear about tax credits etc. he has contributed nothing financially since leaving, I've had to rent a house I can't afford, and he's accused me of sexual abuse because I got pregnant when he didn't want another child!
