I left my DD (1y.o)'s Dad..got myself organised & got the strength, 1 month ago. . 2 months ago he was physically violent to me (grabbed me hard and threw me onto the bed, twice. we were having a misunderstanding/disagreement in the middle of the night). He wouldn't say sorry for the whole next day, and blamed me for making him angry. He eventually did a watered down apology but has since in therapy totally dismissed it as a non-event 'What, I just moved you onto a soft bed..' and also made jokes about Domestic Violence...!? This is what made me leave him..Seeing him make false apologies and have no remorse.
I think he may have some mental health issues..I am pretty sure he is bipolar and he is aware of it too but won't see GP and won't take meds or get diagnosis...doesn't trust them and doesn't want to leave himself at the mercy of the mental health services. He thinks he manages it ok...he is aware of his 'cycle' that he has had for 10 years or more...But still takes drugs sometimes at parties and smokes weed regularly. This is one of the things we argued about as I tried to get him to stop doing this. Sometimes he is balanced and normal and lovely. Anyone you ask would tell you his is so nice & friendly & great with kids, a great guy...But I am the closest person to him (3 years together) and I have seen his other sides. Any sign of stress or vulnerability on my part or too many responsibilities placed on him & he flips out. When he is - as I would describe 'hypomanic' - for months on end especially in the summer...he has boundless energy & goes a million miles an hour, has a tendency to party too much etc, but he also is very irritable, snaps and has a bad temper. Cannot handle stress. I only really saw the full extent of this when I was pregnant with our DD. I hoped he would change or address his mood issues when DD was born. Wrong. Foolish of me. Things got way worse.
Anyway...since we have been having therapy, and my DD is sleeping through the night, and I feel stronger, I said I wanted to separate. He moved out to his Mum's (until my new flat is ready), he has been Mr. Super Nice Guy and offering me loads of help, saying he wants to make sure I am comfortable with everything & he wants everything to be calm and settled for DD and he thinks everything is 'going to be ok' like this. He was doing this being ridiculously nice and respectful and accommodating for a few weeks, then on Wednesday he turned up to look after DD for the afternoon whilst I went to the supermarket and to spend time with her & he was visibly stoned. We had previously agreed, at my request, that he was not to see her when he had been smoking & getting stoned. He agreed, gladly, saying he wanted me to feel comfortable and trust him. He promised that wouldn't happen. (Would have been nice if he could have done that in our relationship!) Anyway, he turned up stoned...I was very calm but told him that was unacceptable & said "I don't know why you've done this, you've really shot yourself in the foot...it's stupid and it's creates mistrust where there doesn't need to be any" He was actually really apologetic and sheepish for once and said 'You're right I'm really sorry, it won't happen again, I only had a couple tokes on my brothers joint and he had made it really strong & I didn't realise, it was a couple hours ago' blah blah blah excuses.
So this afternoon, when he came this afternoon to take her out, he stank of smoke, like he'd literally just been smoking loads or been at a party...his clothes reeked. Maybe just cigarette smoke though I don't know. I think he had just been at the pub as he said he had been watching the football. I was quite oversensitive about it and said 'You stink of smoke?!' and he immediately snapped and said "Oh shut up I don't even want to hear it!" in front of DD ! I said please don't speak to me like that..you seem very angry..I'd like you to leave please" He refused to leave and grabbed DD out of my arms !! I didn't hold onto her as I didn't want her to be pulled so I just loosened my grip on her so it minimised the effect of the grabbing. I then said "You've just grabbed my baby out of my arms, what is wrong with you?" "please give her back to me and leave now" He refused and started having a go at me saying "I've done everything you've asked, I've done everything for you and still you're trying to pick a fight ! YOU should leave, this is MY house!" I said I don't want him looking after DD when he's like this and please can he leave ! Obvs DD is witnessing all this & was upset !
I then said right I am calling your Mum (she lives very close) or the police...or you leave, which will it be?. He walked out into garden with DD to distract her/cheer her up as she was crying. I called his Mum and she was useless but it gave me a chance to hand him the phone so she could talk to him, and at this point I got him to give DD to me. Then he was still shouting at me whilst on phone to his Mum. He hung up on her & I said please, please leave and go & calm down. He was right up in my face, even with DD on my hip. I turned her away from him and angled my hip away from him so he couldn't reach her and I backed away from him and said 'please go I don't want her to see you being like this with me !' He then left but smashed and kicked/slammed both doors on the way out screaming "Fucking bitch I can't believe you're doing this, fucking bitch!!" So loudly so the whole street/upstairs neighbours could surely hear. He was obviously very upset as was looking forward to seeing DD and felt I was witholding her from him, but I didn't want to let him look after her when he was obviously like a coiled spring, so angry etc. Especially given his history. I felt it was right to say no I'm sorry you're upsetting me please leave.....Was I being too harsh??
After he left I was really shaken and upset but pretended I wasn't & DD then wanted to breastfeed for like 30 mins.. I think she was really unsettled. I just let her nurse as long as she wanted & just took time to breathe and calm down. Then me & her had a very normal dinner time, bath time etc & she was happy & relaxed again. Thank god for breastfeeding !!
I have been texting his Mum but not him...I don't know what he's doing or where he's gone. I told his Mum she needs to help him get help because otherwise I will have no choice but to get police involved/limit his contact with DD. Told her his behaviour is completely unacceptable. She tells me he is just very stressed and heartbroken & he is not a violent man but he has his limits. That I should try and remember the joy I felt when I first met him & concentrate on our lovely daughter. Absolutely no help whatsoever. She's probably over there soothing him right now telling him he did absolutely nothing wrong. 
I have called my Dad and he is driving up to London tomorrow to help me with DD and help me pack so I can go and stay with him in the countryside for a while. I can't bear to be here living in his house if he's coming and doing things like this !
I don't know whether this is the right thing to do, whether I should report him, or whether I should talk to him, get mediation, stop him seeing DD altogether, I don't know ?! I don't know what to say to him but I know I feel slightly afraid & like I don't know how things have gotten so out of control and how he seems so unable to take responsibility for his actions or make a change in his life.
