Why do most girls’ think it’s ok for her to do certain things but not ok for her partner to do those things?

Every girl I was in a relationship with barely ever wore my shoes , the same way she expected me to wear hers , when it comes to making decisions. It will always end up in double standards between us. Even after we set boundaries with each other , she will still be selfish and think she is right and never wrong. That’s usually when I throw in the towel on the relationship and move on and realize she is a selfish person , that only wants things her way. Why do females’ have a hard time being on the same page as their partners do? If my girlfriend does something that I feel is wrong and disrespectful , I communicate with her and express my feelings of concern to her , as to why i am feeling the way that I am , she will usually lash out at me and say I don’t trust her or I am being insecure etc. I just laugh and shake my head and say , so it was ok for you to do this to me? but not ok for me to do this to you? Hmmmmm. Usually this occurs when my friends ask me to go places with them , without her , but the thing is , I never exclude her from joining us what so ever , I don’t want to be in a relationship with a girl that we don’t experience and share things together , she becomes my top priority in all my decision making. But when she is asked to go places with her friends? I no longer matter to her , she immediately excludes me. And doesn’t consider my feelings what so ever , her friends become more important to her than I do to her. So instead of arguing with her and fighting with her about it? I just let her go do her thing and I go do mine. Why no longer jump into relationships with girls’ anymore , because
Most of them lie and cheat and try to leave Sucker written on your head while they go out with their toxic friends , they are all Selfish people.

I will not commit to a girl that has selfish qualities in her , if she doesn’t wear my shoes the same way she expects me to wear hers , she isn’t the girl for me. Does that make me selfish? When this is things that we addressed to each other in the beginning of our relationship with each other? I consider myself a very honest guy and and tell her the truth the same way I hope she is telling me. Sadly it is never the case , why I choose to no longer jump into a relationship with a girl.
