When there is no respect in a marriage, it can lead to all sorts of problems. For one, it can be difficult to communicate effectively when you don't feel respected by your partner. This can lead to arguments and even resentment. Additionally, a lack of respect can also lead to infidelity; if you don't feel appreciated or valued by your spouse, you may be tempted to seek that validation elsewhere. Ultimately, a marriage without respect is likely to be an unhappy and unhealthy one.
