Hoping to get some advice on how to help DD with her behaviour. It might drag on but please bare with me.
Long story short my STBXH left nearly 6 months ago for OW when I was pregnant with our second DD. Our eldest is currently 3 and a half and youngest nearly 3 months. He's been extremely inconsistent, forced new girlfriend on our eldest almost straight away and I've had to bend over backwards to try and help him maintain a relationship with both the girls. 6 weeks ago I managed to get him to sit down and agree on how we were going to split time and he sees them twice a week for about 6 hours each time. There's no overnights because 1. He doesn't want them and 2. I haven't pushed for them because he's made it clear he's not interested.
Since agreeing contact 6 weeks ago he has finally stuck to it but our eldest DDs behaviour has completely changed. She's went from being such a care free happy little soul to such an angry child. I felt like I got her through all the changes of him leaving, dealing with the introduction of his girlfriend too soon, the baby arriving etc but since she's had consistent contact she's became almost too difficult to handle at points. Her behaviour worsens when she comes back from seeing her Dad to the point where she actually attacked me tonight and wouldn't stop hitting me. I honestly felt in shock and didn't know what to do. I tried speaking to her to calm her down but it didn't work. I ended up having to force a time out in her room by closing her door and eventually she calmed down and gave me a cuddle saying sorry. But she isn't great at talking about her emotions and I only ever get snippets here and there about what is making her so upset and angry. She started hitting herself when she's annoyed as well and it kills me because when I try to stop her it makes it worse.
I tried speaking to my ex about it for him to take the approach of 'well she's always good as gold with me' or 'she says you shout at her all the time and she doesn't have fun with you' which broke my heart. He literally does no parenting at all and it's more like he's interested in being her friend rather than her dad. She comes home constantly being sick and with upset stomachs because he will let her eat as much as she wants when she wants and when I say to him about it he tells me I'm overreacting and I don't have a say in how he parents on his time. I have worked so hard to encourage a relationship with him and the girls as I am a strong believer that kids deserve to have both their parents regardless of us no longer being together. But I feel like it's almost backfiring and I'm worried about what he's saying to her. He's a massive EA and control freak so I wouldn't put anything past him.
I just don't know what to do and i feel really lost to be honest. I don't know if all the changes have been too much for her or am I looking into it too much, is it a normal phase? How do I handle it best if she does it again? Is there a different contact arrangement that people have found more beneficial to the kids?
Any help would be greatly appreciated so thanks if you made it this far
