I think I see where you are going with this. I think you are saying the hobby does not bring the pain of relationships but some of the pleasure, and that's a big advantage for some.
In most relationships, men don't idealize the woman they love as a "perfect mate" and then are disillusioned later. They have more sense than that, as do women It would be really hard to be that close to someone and not know about their flaws as well as their strengths. Well before a breakup happens, you know that about your loved one.
There are few surprises in break-ups, even if there is infidelity and that comes as a shock, because, on reflection, in time, most reasonable people will admit there were signs and symptoms that the relationship was in trouble -- and the ending of a serious relationship is usually a gradual process, even if it feels abrupt at first. People grow apart, sometimes.
It's never fun, but I don't think "pussy payments" come into it. That would imply that there was some sort of inequality in relationships, with men having the upper hand, entitling the woman to some kind of compensation after a break up, when really the balance is even on both sides. We've come too far for that

Women share the responsibility of making the relationship work. One person or the other is going to wish for something different, maybe for it not to end. But I don't know that it follows that the person is going to be vengeful about it.
Relationships do not die because one person killed it. Are monetary payments involved, in some cases, of course. When it's fair. Some men get alimony. Would you call that a penis payment? No. Women get alimony to reflect the contribution they made to the marriage, when that is the case, or to offer them a chance to be successful on their own, get them on their feet, when their is a wide inequality in incomes. The children get support, which is fair. I've been divorced and the process isn't fun or perfect, but it can be fair.
One thing I do know: getting lost in blame and bitterness is a dead-end. There's no way to learn or move on from that. And moving on is the only thing that makes an ending meaningful, that and what you learned from it.
Also I think intimate relationships should not involve tests. It's so much easier to just be authentic and real about your feelings, and considerate and honest if they happen to change.
