Phew! namechange worked!
I have kicked my partner out (has been coming for a while I guess) but now I'm feeling like I might , just might have made a mistake, not sure. Maybe what I'm feeling is just a wobble.
Basically we had been together for 5 years. Problems started about 2 years in when we moved in together, reason being he found it difficult to deal with becoming a step-father to my DD from a previous relationship. We went on to have a child together (now 1) and things have got even worse from there.
He is great with both kids practically and never leaves DD out. However he has always made it clear to me (in private) that he finds every day a struggle having to deal with a child which is not biologically his. Obviously this has hurt me and this issue has been the sole cause of 99% of arguments between us.
DD has been particularly badly behaved recently and I have been really tired with starting back to work after Mat leave ended.So the other day after the school run I commented to my partner that I was sick of DD misbehaving and I can't be bothered dealing with her at times. His response: "Well why don't you just send her to live with her dad and we will live happily ever after?" 
e then said why was I surprised , haven't I always known that he struggles to deal with DD, he loves me so 'puts up with her' and that he thinks I would be happier without her (wtf!!!!!) but of course he wasn't advocating I get rid of her, he "didn't really mean it like that" 
So I kicked him out of the house and he is living with his brother. He cried as he left, but I said if he really loved me he would never dream of hurting me by saying those things, so we are finished.
I'm now regretting it a bit (crazy I know) as he did try with DD and outwardly had lots of patience with her and time for her (went on walks with her, built toys for her etc) - just inwardly he struggled and I think he was taking it out on me, which is obviously wrong, but would counselling have helped in this situation or is he just an abusive twat for saying this?
I just don't know anymore
. I have a really stressful job working with adolescents with mental health problems, some of the clients will make insults about my appearance and physically attack me and I used to live for the end of the day so I could go home to some company and dinner, but now it's just an empty house and I feel so empty and struggling to cope 
Sorry about the essay x
