In USSR for example (after WW2) it wasn't uncommon for women to tolerate men cheating on them and being content as long as he always returned home. As you might expect it was due to a big gap in male to female proportions that even shifted cultural beliefs and cultural tolerance. If my sources are correct it is mostly like in Europe and US now again but some rural places still cling to this.
My point is value yourself and understand the natural gender dynamics. Women aren't bad or men aren't bad generally it's just a supply and demand market is skewed.
Sorry for the long a** lecture
