Domestic abuse

I wish I never told social services anything about how my partner is,what have I done! I feel so guilty about it all! I can't trust anyone! He rang to speak his little girl and he sounded so nice and was so nice about my kids! I didn't realise it was domestic abuse until social services said! To have to watch my little girl cry coz she misses her daddy is so painful to watch wen he is being so nice on the fone! He regularly swore at me called me names and verbally abused my kids,shouting screaming smashing things up going mad wen I didn't give the answer he wanted,making me feel useless,only really talking to me wen he wanted,hiding or reading under the covers watching me work my arse off in the Hm wen I had pneumonia! I feel so lonely :-/
