Not sure if right place to post this, first time posting on here. I am almost 7 months pregnant with my first baby and me and my daughters dad have split. He is threatening to contact a solicitor with his family and take me to court for 50/50 from the second she is born and because i have refused this and tried to come to an agreement until she's older, he's saying that I'm using our daughter as a weapon. I have expressed that for the first few months of her life she will need to be with me as she's all I've known for the last 9 months and that I am going to be breastfeeding he's saying I'm just using that as an excuse and babies get taken off their mothers all the time and they turn out fine, aswell as saying to just pump or use formula so its no "excuse" at all to keep her away from him.
I have already said he can have visits twice a week for a few hours a day as well as his family and as time goes on and she gets older he can have more days and start taking her out in her pram to visit other family members at theirs instead of visiting at my home. I'm not comfortable letting him take her and have overnights until we have established a bond and have her in a routine, as well as him stopping smoking weed in his flat but he starts getting mad saying I'm keeping her away and excluding one side of her family. I've already said they can come visit they just have to arrange it with me as I'm in a separate town to him and I don't want them to have a wasted journey if I was out. For the entirety of my pregnancy he has been smoking indoors and refused to go outside to smoke, the most he will do is sit at the back door (in a downstairs flat) in the same room as me and told me if it bothers me so much to go into a separate room. His mum has made a joke about it and said she can't believe I'm making him do that and she smoked throughout all her pregnancies and her kids turned out fine. My ex and his mum have also gone on Facebook and started slating me calling me a narcissist and a bitch as well.
Im sick of being threatened and I just don't know where I stand at the minute, if he takes me to court will he get granted 50/50 joint custody from birth? I'm not saying I wouldn't grant it in the future, but until I've stopped breastfeeding then I wouldn't want that for her, it's not in her best interests to be passing her from house to house every week. I also would not be able to afford a solicitor or to go to court for that matter if he does go that route. He has said he will do everything in his power to get her taken off me if I don't agree to his "demands" and that she will realise when she's older the "truth" and that she will end up hating me. I'm terrified of having her taken off of me so I don't know if I should let him have what he wants, even though I know this isn't what's best for our daughter, but I can't keep taking all the threats and the nastiness from him saying I'm using her as a weapon and that I'm going to be a shit mum. I'm just stuck and hurting at the minute, I don't want to lose my daughter, I just want her to have both parents in her life and not for her to hate me because of what hes made me out to be to her aswell as his family, just because I didn't let him have her from birth.
