Okay so bit of a long post but didn’t know where else to turn and get so advice or even just someone in a similar situation.

So my partner and I have been together a bit over 12 months now, and he has three kids to a previous relationship. 2 twin girls aged 7 and another 3yr old girl. His previous relationship was extremely messy and that came across into ours. They were together on and off continuously over ten years will multiple short term partners between. But the ex baby mama has just been total drama from day dot. Like messaging my ex partner, my family, my partners family, my friends, his friends. Just anyone she can to bad mouth me and make me be out to be this “homewrecker” (Ps. The relationship ended 4 months after the last one was born and only lived together in separate parts of the house to maintain “normal” life for the girls til they both found new partners). In the beginning she broke into my house and planted a pregnancy test to try scare my partner into leaving me because he didn’t want more kids (with her). She has gone to the extent to steal his keys when he picks them up so he’s stuck there so she can message me and make up total bullshit. Every time hes with mates she will message me saying she’s having a great time with him and I should have seen this coming and blah blah. Even when I’m there with him 95% of the time. We both have her blocked on all social media because she’s just crazy sometimes but still always comments on our life and things we’ve recently done. She has downloaded apps to create fake text conversations between her and my partner. All trying to scare me off. Everything began to settle down even though I still had never met his children. And so I agreed to meet with her so she could “build trust in me and get to know the person that will be around her children” I went and everything was great and we organised a day to go have pizza in the park as a neutral meeting. And not even 24 hours after meeting up with her all my partners family are calling him going off saying ex baby mama told them all the horrible things I said about them and how excited I am to take her children and have my own little family. Mind you I am 20 and had no intentions of every falling in love with a 28yr old single Dad of three. And the ex is 37 and carrying on this way! As time has gone on things have slowly gotten a little easier, my partner has seen his girls 6 times and now she has agreed on him having them every second Saturday and Thursday but no nights. She has so many ridiculous rules to him seeing them and every time they come over she always calls after we drop them home and has a problem with something. Eg. I’m not aloud to drive MY car with the girls in it. (Car seats only fit in my car) I’m not aloud to be at school pick up or pick them up alone. I’m not aloud to change nappies or bath them. I’m not aloud to be left alone with them or be in their bedroom in MY house which I own not their father. I’m not aloud to do their hair. I’m not aloud to sign off any homework. They are not aloud to call me Maddy because it’s too close to Mummy, but they don’t even call her mummy it’s mumma. I have to be called Madison. I am not aloud to show any affection toward the girls. And my partner and I are not aloud any affection in front of the girls, we arent aloud to go into rooms alone from the girls or go to bed in the same room if they are here. I’m not aloud to take photos or be in any photos with them. She talks down about their father and I infront of them and quite often the twins come out with things like “my mumma said you stole our daddy and that’s why he doesn’t love us” “my mumma said daddy only loves you cause your not old and has big boobies” “my mumma said daddy will leave you too cause he leave everyone” “my mumma said you can’t tell me what to do and I don’t have to listen to you”She is honestly dragging all happiness out of my relationship with my partner and makes me fear falling pregnant as to what she would do. We are TTC and all this is just getting so much and making me resent having children with him. He is the love of my life and I can’t imagine being with someone else. I was with someone for 8 years prior to this relationship and I know I’ve found my one. But I just don’t know how to over come this baby mama drama. Am I being a sook or is this bitch so over the top. I can’t even deal some days. I honestly spend a lot of time hiding or doing other things when the girls are here because it’s easier not being present then constantly belittled and made a joke of. Someone please give me advice.
