Conflict

I'm struggling with my avoidant partner for 2 years now. She has a son and I'm okay with the kid being there to the point that I want to treat him like my own but she won't let me. We have been together for 2 years for 6 months, there were ups and downs. She always does the silent treatment and stonewalling when I try to open up things. I can't cry because she'll get mad and I can't open up too. When she got a new job, she decided to move back to her hometown to take care of her son. I struggle with LDR because of the communication issues. I disagreed with it but she got mad, and at the end I had to agree to it. Recently we had a fight because I expressed my needs and I wanted to set a boundary. She got incredibly mad, defensive, and in the end I had to be the one to apologize but at the same expressed that rather than being a safe place, this is happening. She's doing the silent treatment on me again. I have friends and family, but I didn't want to becomea burden. I'm depressed and drained, anxious with all the overthinking, and honestly that's why I'm here. The years of being in this type of relationship where I carried all the weight. I'm struggling.
