Gf and wife can sometimes be completely different games. You are 19 according to your profile, so I will assume this about a girl you are dating or girlfriend.
Disrespect is usually some sort of test. Dont be angry at women for testing you, if they didnt do these tests, their body count would be astronomical.
Every time you fail a test, her attraction for you will lower. Every five tests you pass, her attraction will possibly and probably increase.
You must be willing to walk away. If disrespect happens just say something along the lines of "Im not sure if you think Im a some sort of pushover or what but disrespect is a dealbreaker for me. Nip it in the bud or Im showing you the door". I just made that up with random words, Chatgpt can probably give you something better.
Remember, with women you have to punish bad behavior and reward good behavior. When you pass the test you might not get laid that day (or maybe you do) but will get laid more frequently in the future. If you fail a test, you might get laid that day (or maybe not) but her attraction for you will be lower because you failed the test and it will continue to get lower and lower (along with a decrease in sex) if you keep failing tests until she eventually ghosts, breaks up with you or monkey branches etc
