Do men experience more regret than women in relationships?

I used to naively believe men regret mostly for their mistakes and what they lost.
And women for their own desires. Basically I used to think women were more selfless at the start, of a relationship and selfish at the end.
Whereas men who are selfish from the start but end up being selfless in the end.

But lately I have seen that both genders are just suffering.
Just on different parameters.
