<human>: Hey everyone. First time posting here (had to create a throwaway for this). Looking for someone to share an impartial view on this situation with me. I dont live near my family so i dont feel like I have anyone i can talk to about this. 

Me and my fiance have been together 4 years and have 4 kids together (1 of which is biologically mine. All of which i love like my own).

We are having a really hard time at the moment. We seem to argue relatively frequently, but its not an issue of frequency, but potency. What starts as a small thing seems to get blown out of proportion and my partner threatens to break up with me everytime things get tough.

 If i try and keep calm and talk about the issue, im controlling. I am never right and am always the one thats at fault. I feel like i have to walk on egg shells all the time around her. Because anything i say can be taken badly and dissolve in to her trying to take my daughter and threaten to break up with me. I dont know what to do. How much of myself do i bottle away till there is nothing left of who i am for the sake of holding the relationship together.

I love my partner and when things are good, they are great. But things just turn around so quickly at the drop of a hat. And the thought of not being around my kids, kills me.

I moved quite far to be with her so im not near any family or friends. So i have nowhere to go. Can anyone offer some advice.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: relationship on the verge of ending. I dont feel like anything i try works and i cant bear the thought of losing her or my kids. Help!
