Boyfriends mother causing issues

So my boyfriends sons mother hates his side of the family. Will threaten to stop allowing my boyfriend from seeing his son if his family sees him during our time with him. My boyfriend has told his mother over and over again not to post on social media about his son and not to cause problems with his sons mother for the sake of him seeing his son....

So we get a call Saturday saying that her mother saw a picture that my boyfriends mother posted of their child and his cousin. We had gone to the mall earlier that day to allow them to play together. She accused us of not spending time with his son and that we just drop him off to his mom. Which we have never done. And she then proceeds to say her mother (their sons other grandmother) is gonna take both my boyfriend and her to court because she can’t trust them.

Then we get a call from her mom telling my boyfriend she never said that. That she did question why his mom was posting his son when he’s suppose to have him. Again we were all there. And then goes on to say that her daughters new husband is abusing their son and that’s what she meant by taking them to court. In which my boyfriend said no I will take her to court. In which the grandmother flipped out saying she should have full custody and that she will allow my boyfriend to continue weekend visitations 🙄

(We are now at court filing an ex parte and a parenting plan with his sons mother)

Anyways so he flipped on his mom for posting and tells her if she continues to cause problems for him that she won’t see his son anymore. They don’t have the best relationship as it is but this is the breaking point. She told him she doesn’t care what her family says that she can do what she wants. Okay cool no more seeing his mom then. Regardless if it’s right or wrong it causes problems and she doesn’t care.

Then later that day she apologized to him and started asking weird questions. She asked when we dropped his son off. She asked why we could eat out but couldn’t buy him an ice cream at the mall. He said we don’t need to have a reason, that ice cream isn’t that important and that his son needs to know just cause we go out doesn’t mean he will always get something. Then she continued saying oh but I bet you spoil her kids, referring to my boys. And he said no none of the kids get spoiled. Then she asked him when he plans to marry me or if he’s just gonna continue to have bastard children. WTF?! Now at this point I’ve had enough. She’s laughing like it’s a joke and I told him at that point I don’t want her near our daughter when she’s born which he agreed to.

This whole situation is ridiculous and idk what to do anymore. Going to court is gonna be a process and huge fight with his sons mom and grandmother. But now we are also looking at the possibility of his own mom making matters worse for us. I’m almost 38 weeks pregnant and so stressed over all of this. We will be finding out soon if we get granted emergency custody until a scheduled court appearance. Either way I’m not ready for what’s about to happen.

Sorry I just needed somewhere to rant and if anyone has any advice or who has been through something similar

Update ::: . We were recently told that his sons mothers husband has been abusing their son. So we went to court to file and ex parte and custody agreement. So moving on yesterday the sheriff served the mom with court papers and she freaked out. She called my boyfriend asking what he did and why this was happening. He said he didn’t feel comfortable talking about any of it until they went to court. At this point we are ready for her to flip out. But the complete opposite happened. She said her husband didn’t like being accused of hurting their son and that he never did anything to him. However he wants to move out of the state to his family and she wants to go with him and the child they have together. My boyfriend ready to snap saying your not taking my son didn’t even have to say those words because she said he can have him. She said we can have their son if my boyfriend agrees to let him call her whenever and allow her to see him on vacations. Again my boyfriend said they will talk in court with a mediator. She said okay and continued to ask if the dec 12 court hearing was the only one they had to go to if they agreed on everything. He said they won’t know till they go and she said well either way she’s leaving on the 16th! That’s 4 days after court. She’s just gonna leave. This whole thing is crazy to me. If they weren’t guilty of abuse why are they running?! So now we will have 4 kids full time. I’m so happy for my boyfriend but im so overwhelmed. My boys are 4&3 and his son is 8. It’s gonna be such a change and I’m nervous. Plus I don’t know how to make the transition the best for him. I know he loves being here with us and loves my kids but it’s obviously gonna be different. He’s use to having fun every weekend but now he will be here all the time with all the kids being treated the same. I just need advice on how to make this work because I know his mom leaving is gonna hurt him. He hates her husband but obviously loves his mom. And his mom is choosing her husband and new baby over him :(
