Ex's girlfriend too insecure 🙄

I'm just done with my daughters father.

I'm trying to get along for our daughter, I'm trying to get along with him, his girlfriend, his parents, everyone. But its impossible!

Little back story on why we broke up: I was pregnant, everyone knew about it, he was in school, and this girl approached him, really interested in him, they flirt a lot, and end up sleeping together, I find out, and break up with him, this girl knew I was his girlfriend and that I was pregnant. Once they slept together she started messaging me, threatening me and telling me to back off cause shes not going anywhere. Like okay there psycho.

Anyway he wasnt in our daughters lives until a few months ago he serves me with papers to go to court, like alright, even though i always had the door open for you to see her, my only request was for him to visit her periodically first so she gets to know him, but his new girlfriend had a problem with this, shes the reason he stopped seeing her in the first place. Anyway its mandatory to try mediation first before going to court, so that's what we're doing now, and guess what our mediator told him, he cant just take her, he has to come visit her first until she warms up. So we agreed in mediation for the first month he'll come visit her twice a week for a few hours and video call her at least once a week. So for those first month he came to visit once a week, except one week and never video called her ever. And whenever he came to visit, he brought his girlfriend and her daughter. So during those visits our daughter never got enough attention and basically she never got used to him at all, she only got used to his girlfriends daughter. So we go to our next appointment and I say that he hasn't came enough and our daughter isn't warming up to him at all because of them coming too, so the mediator tells him to come alone at least half the time, he agrees to it, she also told him that he needs to come twice a week and video call, again this didnt happen, and he missed another week of visiting, no surprise. Anyway they came to visit 3 weeks ago, at the end of the visit her 4 year old says that her mommy doesn't like me, I mean I get it, his new girlfriend doesn't like his ex, what else is new? But to bad mouth me in front of her daughter at home? I have a problem with that, like what are they going to be saying in front of my daughter, and the last thing I need is her daughter saying "my mommy doesn't like your mommy". That would be putting my daughter in a very uncomfortable situations where she feels like she needs to pick sides, I dont want that. Like previously to this I thought we were all getting along fine, in fact I actually really like her! Anyway the week after, they never showed, and this week I asked him to come by himself because I'm not feeling well, at all, and he actually came by himself, but he had to have his girlfriend wait in the car with her daughter, yes, shes incredibly insecure, his phone was also blowing up the entire time he was here, so he never spent any time with my daughter at all, yes it was her. He asked to see our daughter again tomorrow, I said yes, but since I'm still not feeling well I'd like it if he came alone again, he agreed to it at first, but he messages me later saying hes not comfortable coming here by himself yet. Like okay, this is getting ridiculous. He obviously has no issue coming to visit by himself, he agrees to it all the time, I'm very respectful, I have never flirted, or tried to get with him, I keep my distance and respect their relationship, I don't want him anyway! It's very clear that she has real issues with him being around me, and it's really bothering me now, she walked into this relationship with her eyes wide open! She knew I was pregnant, if she didnt want to be in this situation, then maybe she shouldn't have pursued a man who she knew was having a baby soon. Now my daughter is going to be the one hurt, because she cant get over herself. I dont even know what to do at this point, he went back on almost all our agreements, and it's clear that they talk negatively about me around her kid. We have another mediation appointment coming up next week, and I plan on bringing this up, but our daughter is no where near ready to go to his house without me yet, she had a full blown panic attack today when she thought she was going with him! I dont know how we're going to keep doing this, and I really dont want to go to court.
