Healthy ways of going no contact with parents?
So my situation with my parents and to some extent my younger sister has grown increasingly more difficult to maintain because in a simple sense my parents refuse to let me have control over my decisions in my life. They do not approve of my girlfriend that I have been happily dating for almost 3 years now and they have made accusations of things that happened at my 30th birthday last year. Because of the situation and wanting to get facts straight I asked other people who were at that party if they had heard or seen the things that my parents were accusing my gf of and none of them said that any of that happened. When I brought that to my mom and dad they said that I can’t believe them because they’re just being nice to me and don’t have the heart to tell me the truth. Extremely manipulative talk and for about a month I didn’t talk to them. Unfortunately part of me really wanted to fix things and the month of no contact was killing me because I had always felt so close to my family (it was also around Christmas so I was in a forgiving mood) so I tried to find ways to resolve the issues. It went okay for a few months though whenever there was mention of my gf they would just ignore it. But as of about a month ago my gf and I are closing on a house, which pissed off my dad because I didn’t include him on stuff. He had known I was looking and wasn’t happy that I was doing it with my gf (he’s a finance guy and thinks with numbers and not happiness). He was outraged why I wouldn’t consult him and I told him I needed to do this on my own because I knew he would micromanage every part of it and would try to get my gf out of it. For context my gf and I have been living together in a rental for almost 2 years and have had 0 issues. At the mention of me saying I intend to propose to my gf my dad immediately flipped on me and called me pussywhipped. My mom also instigated the argument and said I have been avoiding them because she’s been telling me not to, even though she’s been the one telling me to talk to them and try to find middle ground with them by telling them the truth about how I feel. With all this said, what is the best way to handle this all? Therapy is definitely on the horizon but am I wrong in wanting to cut ties to them? I want to find middle ground because in my heart I still love my parents but this is breaking me down.
