Did I make the right choice

My ex and I have been together for 5 years. Lovely beginning but we went through a lot of shit and decided to work on it.

Days before her birthday she decided to go in my phone and get upset about something she already knew that happened last year, which was weird to me.

Fast forward to her birthday every year she’s always complaining about how her birthday isn’t right and she always flips on me at the end of the night when in reality I’m the only one there for her. Her own mother didn’t even buy her a cake. Anyways we went out that day argument got so heated I left.

After that we grew so distant like I could just feel it.

She started hanging out with new friends , i send her money to have a good time. She can’t even pick up the phone also she has no job right now. So basically I’m taking care of the both of us. Anyways she gets picked up at 11pm to go to the overlook and drink she didn’t come back home til the next day 1pm.

Lied about going to jail , and I have actually been and I had disappeared due to me not being able to contact anyone so that made me feel some type of way. I still stayed I don’t know why I shouldn’t left when she didn’t come home.

Last straw was, her brother and her share a bathroom he’s disgusting so nobody cleans the bathroom. While I’m at work she asked me to leave the house and my car so her friend could come over for a girls night. Im also a girl too… so after I got off I came back home and she was cleaning the house spotless something she rarely does specially the bathroom because her brother is disgusting as hell. Thought that was funny and just took the hint she was cleaning up for company.

I packed all my shit went to spend time with friends and I have been 1 week no contact.

Please guys I need some words because I feel to deeply and sometimes I think I make wrong choices help a girl out
