I don't know what to do anymore?

I'm so confused, I don't know what to do anymore. Myself and my partner seperated back in July, we've managed to make things work out and we're back in a relationship. We seperated when I was 6 months pregnant, he walked out on myself and our 1 year old daughter. We both went back to living at home with our families - myself and both daughters live at my parents house; we see him on weekends.

We seperated because of he's family planning there wedding on our daughters 1st birthday party (not the day of her birthday) and him picking to go there rather than be at her party and him picking hes family over us in general. Also due to hes mum always trying to control everything and when I was picking up my partner from the wedding to organise our daughters birthday food & decorations hes aunt was screaming in my face, being threatening infront of my daughter whilst i was 6 months pregnant. - this happened at hes mums house.

As I said we've worked things out and we're back together. But hes mums already starting to try and control everything and is demanding that I go to their house. I dont want to go there for the first time seeing them as the last time i was there I was being screamed at. I came up with the idea that we went for a coffee and thats not good enough. There that adamant that I go there that they've said i can bring my mum if it makes me feel better.

I just dont know how I feel about the situation, nothing feels the same. I just dont know what to do?
