Boomerang Relationship.Help last night I ended my boomerang relationship of 7 years. ?

We have split up many rimes over the years but the last time he fathered a child and told me it was my own fault cause I threw him out.I already knew he had son of 12, but recently during an argument he told me he had a sun of 26 he cant undrstand why I could be angry about him not telling me. He does not get on well with my own children and is jealous of them and everyone who comes into contact with me. He has attended anger management in the past to no avail.I lost all my visitors to my home and could not recieve atext or go on the computer without him being suspicous of me/ I know Ive done the right thing but feel very low right now Can someone give me advise on how to move on and be happy and laugh again.
